Re: HELP PLEASE: Acting drunk but not drinking?
I can tell you, in the first few weeks after my uncle quit drinking, his behavior was quite erratic. He wasn't acting drunk, he was just acting WEIRD. He took me and his dog out on this "hike" off road, hunting game poachers. (I have no idea why.) Eventually his brain chemistry leveled out again.
Definitely, investigate it. But it's possible his brain is just out of whack from the lack of substances it's accustomed to.
