Just that, really.
Am currently on medication which seems to interact with alcohol- partly by increasing my desire to drink. I do really like a glass of wine of an evening, but have trouble stopping there. I remember reading an article a few years back where a hypnotist was able to reproduce the pleasant effects of a drink for the subject when they drank a particular chosen soft drink- and they were able to just 'park' at that level of merriness, too.
TIA!
