What egos did you comprehend in relation to your fall? More important than what you physically consumed, what impressions did you ingest but did not digest psychologically? Lust is the cause of sexual downfalls. If you are giving your conscious energy to lustful egos, then pollutions will continue to occur regardless of abstaining from certain drinks. Diet has some role in relation to how much fire (tejas, red meat) you consume (or if you accidentally eat pork for that matter). Too much tejas that is not transmuted can give rein to lustful aggregates. However, if you diligently comprehend and eliminate lust, then there is no problem.
