Since about two years ago, when I drink large amounts of alcohol, I frequently black out. Two years ago the same amount of alcohol would not do this to me. Also now, I stay drunk for several hours after I wake up, and sweat out alcohol (no matter what it is I drank, it smells like vodka) for a good twelve hours AFTER I wake up. If it's anything to add, I used to take LARGE amounts of valium and vicodin (but haven't in a few years). I'm 21, about 5'9 and 170#. I'm just concerned and a bit freaked out more and more lately. Any advice? Also, anyone in the military? I am, so it makes this problem fairly delicate to tackle.
