I've always been a regular, although not massively heavy drinker. In the past year, I have been much more adversely affected by alcohol, starting with extreme sleepiness and now at the point of extreme sickness the day after a few drinks. I had 2 g&ts last night, after 2 weeks of abstinence and it's wiped the whole day out for me! For context, I'm 31, no sudden or recent weight loss or anything else that might have affected it. Has this happened to anyone else?
