When I worked for C&L, then PwCC, and then the sweatshop that is IBM BCS, there was a huge culture of heavy drinking. I've heard stories of marital affairs, unwanted pregnancies, and even come across one suicide after a drinking binge on a client site in Holland, so alchahol can cause real problems if you don't manage it.For short term remedies, try something like taking Milk Thistle on a regular basis to strengthen your liver, or mix your drinks a bit: who know's whether there's any real vodka in that Vodka and Coke you're drinking. Most bar men are discreet enough to manage this for you. Good for you that you've picked the risks of this up, so early on in your career.
