The temperance movement is, unfortunately, very much still alive. So trying to find independent, reputable, scientific research is almost impossible.
You say you feel you're drinking too much and I'm curious as to the reasons. Do you live somewhere where "the demon drink" is view with negative connotations? Or other people are trying to pressure or persuade you to reduce your drinking? To which I'd suggest you tell 'em to "Go Forth and Multiple".
Perhaps you are experiencing side effects (be honest with yourself)? beer-belly, mood swings, hangover, etc. Then I'd recommend you change how you drink or even reduce the amount. Drinking 3 pints in a day is not normally a problem. But a day is 24 hours. If you're trying to drink 3 pints in 1-2 hours, that's a problem.
I don't drink, not because of ideology or "health" reasons. But simply because I find most alcoholic drinks have an unpleasant taste.
