My guy and I have been together for 2 years. He is a young guy, only twenty-three. On a light day, he would drink 2-6 beers, and on a heavy day, no less than 6. He has decided to give it a rest for a while. The first 1 1/2 we were together, he was always really docile, fun-loving guy but in the last six months he is VERY tempermental, frustrated, anxious, etc... I think that he is having some health issues that are the main component for his this, but I think alcohol has begun to aggrevate the problem. My brother said he read that a heavy drinker can actually develop an allergic reaction to it, causing the adverse effect that alcohol usually is accredited for. (Alcohol is a downer, so tempermental and anxious would be that adverse reaction) Does anyone know about this, and can explain it to me a little further.
