No, drinking gives you power. It numbs your inabitions and makes the weight you were struggling with look like a turd in a bucket.
I used to smoke weed and lift becos it did the same thing, until I relised I may as well smoke 10 cegerettes just before my work out.
What alcahole does is retards growth, and makes your muscles small.
Smoking ciggi's thickens the blood and makes it hard for any real growth or recovery becos of that.
However I did have a very muscly mate who would drink a beer half an hour before a work out becos it gave him a great carbo energy rush.
