Thanks for all the replies.
Melinda, yes I've been concerned about damage to my brain from drinking for a short while now, especially with the hangovers. I don't know why it just occurred to me that the years of abuse jolted my brain outta whack. Brain fog maybe? The desire to fix everything yesterday maybe. I guess I need to learn some patience.
It would be nice if we could explain this to those around us who don't understand. "Sorry sir/mam, but I want to bite your head off right now for no particular reason whatsoever. Don't take it personally." 😉
