Don't know what you were on and all of that, so time's tough to predict. Nights seem to be the rough spot for most of us with sleeplessness and w/d related anxiety, so I feel for ya man. I'm happy for you though, hang in there, it WILL get better, and it gets better all the time.
You should feel better in a few days. the first couple days are rough, hang in there it does get better, I promise.
Did you look at the amino acids on the Health Pages? They are at the top right hand of the page.
Good luck and keep posting!
How many days are you off of them? How much were you taking?
