I have tried all sorts of suggestions including those above. My problem is that even after one pint of a very weak lager or bitter, my stomach is in knots and I feel the need to vomit and if I don't I feel queasy for around about 8 hours. My options: don't drink. WM's is the best advice.
Not much fun for my friends, but I can still have fun and the odd drink occasionally. As dinga said, it is your body telling you something is wrong and my GP is still trying to find out what mine is saying, including probes in unmentionable places.
Not drinking may be slightly embarassing with the usual digs and taunts, but not as embarassing as being sick after a pint of Fosters.
