"Alcohol lowers your inhibitions, so you relapse" sounds like a sentence with a study behind it. Half of it has one. The half about alcohol is well measured; the half about pornography has never been looked at.
What alcohol has been shown to do
Acute alcohol impairs the ability to withhold a response that is already prepared. Across human laboratory studies the effect is g = 0.41, larger at higher breath alcohol concentrations and larger when the task has first trained the response you then have to stop. Separately, across 30 experimental studies, drinking raised people's stated intentions to have unprotected sex — d = 0.24 to 0.35 — and the effect was bigger when sexual arousal was already high.
The usual explanation is alcohol myopia: intoxication narrows attention onto whatever cue is nearest, so the immediate thing wins against the distant consequence. That is the leading account of those findings rather than a finding of its own, and alcohol expectancy — what you believe drink does to you — remains a live rival explanation.
Notice what the outcomes actually are. One is a reaction-time task in a laboratory. The other is a rating of what someone says they would do, about partnered sex. Neither measures a sexual urge, and neither measures any solitary behaviour at all.
What has been tested on pornography
Nothing proximal. A scoping review searching four databases to December 2024 screened 949 references and found eight eligible studies, every one of them cross-sectional. Alcohol was the most frequently studied substance and was positively but weakly associated with problematic use — and in the study that adjusted for age and gender, the association did not survive the adjustment.
The nearest thing to a real-time test is Borgogna and colleagues' 2025 fourteen-day daily study of 113 men, 1,240 observations. Baseline alcohol problems predicted neither how much pornography the men used nor how much trouble they had controlling it. The correlation between problematic use and alcohol problems was 0.08; with depression it was 0.29. That is a null. It is also, strictly, the wrong test for this question — it asks whether people with drink problems use more, not whether tonight's drink raises tonight's urge, and nobody has run that one.
The trigger list nobody put drink on
The one systematic catalogue of what people trying to stop say triggers them comes from the analysis of 104 abstinence journals. The external cues it records are electronic media and social feeds, seeing attractive people in real life, and being alone in your bedroom; the internal cues are chiefly negative affective states. Alcohol is not on the list. It appears once in the entire paper, in a table of demographics, as a self-perceived co-occurring addiction reported by one member out of 104.
That absence is the most useful thing on this page. A trigger claim that turns up in no experiment and in no catalogue of self-reports is an assertion, however often it gets repeated.
What to do with that
Take your own pattern seriously anyway. If you have noticed that drinking is when it happens for you, that is a fact about you and it does not need a study's permission. It is just not a general finding.
The reason to settle it in advance rather than at the time is separately established: intentions on their own translate weakly into behaviour. Increasing the friction of a behaviour — moving the cue further away, breaking the sequence that leads to it — does reduce how often it occurs, though that evidence is graded low-certainty and comes mostly from short laboratory studies of food.
Be careful with the mechanism story, because it is the part that sounds most like knowledge. The four-part loop taught everywhere — cue, craving, behaviour, relief — is a teaching model from popular behaviour-change writing rather than a finding, and whether a craving is even a necessary stage in it is the contested part. "I drank, so my brake was off, so it was always going to happen" is that model plus a laboratory reaction-time result, stretched across a gap nobody has measured.

Sources and how strong they are (5)
- AnecdotalWhether drinking makes a pornography urge more likely has never been tested. There is no alcohol-administration experiment, and no event-level or daily study, with pornography use as the outcome. The whole literature connecting the two is eight cross-sectional surveys, in which alcohol is the most-studied substance and is positively but weakly associated with problematic use - an association that did not survive adjustment for age and sex in the study that tried it, and that did not predict anything in the one daily-diary study. Alcohol does not appear at all in the only systematic catalogue of self-reported triggers in this population. Someone who says drinking sets them off is reporting their own experience, which may well be accurate for them; they are not reporting a finding.

- Well establishedAcute alcohol impairs the ability to withhold a response that is already prepared, and causally raises stated intentions toward sexual risk-taking. A meta-analysis of human laboratory studies puts the inhibition effect at g = 0.41 (95% CI 0.35-0.47), larger at higher breath alcohol concentrations and larger when the task has first established a prepotent response. Across 30 experimental studies, drinking increased intentions to have unprotected sex (d = 0.24 to 0.35), and the effect was larger when sexual arousal was already high. The usual explanation is alcohol myopia - that intoxication narrows attention onto whatever cue is most immediate, so the near cue wins against the distant consequence. That is the leading explanation, not a separate finding, and alcohol expectancy remains a live rival account.

- AnecdotalA qualitative analysis of 104 rebooting abstinence journals found abstinence felt impossible at first and became attainable with cognitive-behavioural strategies plus social support. The benefits members attributed to abstinence were a regained sense of control over their use, and improvements in mood, energy, mental clarity, focus, confidence, motivation and productivity, less emotional numbness, and social and sexual functioning. Sleep is not among them — the paper's only mention of sleep is a healthier sleep routine adopted as one of the lifestyle changes made to support abstinence. The same paper is also the only systematic catalogue of what members themselves say triggers them: external cues (electronic media and social feeds, seeing attractive people in real life, being alone in one's bedroom), internal cues, chiefly negative affect, and the "chaser effect" — cravings that follow any sexual activity engaged in during abstinence. Alcohol appears nowhere in it. Self-report only; third variables not ruled out.

- Mixed evidenceIncreasing the friction of a behaviour - moving the cue further away, reducing availability, breaking the sequence that leads to it - reduces how often it occurs. The direction is consistently found and the effects are moderate, but the evidence is graded low-certainty, comes mostly from short laboratory studies of food, and has never been compared head-to-head with intention-based approaches. What is separately well established is that intentions on their own translate weakly into behaviour.

- Mixed evidenceHabitual behaviour is usefully taught as a four-part loop — cue, craving, behaviour, relief — in which the relief reinforces the cue-behaviour link. This is a teaching model from popular behaviour-change writing, not a finding. The established science underneath it is narrower: habits are context-response associations strengthened by repetition in a stable context, and whether a craving is a necessary stage is exactly the contested part.
