good for you!!! whatever you do...dont, dont, dont use again. you may not get so lucky next time. I experienced the same thing (no wd's) and FOOLISHLY thought that I could use again and stop with no problems...now look at where I am...20+/day and trying to stop.
my dad recently told me that there is "no such thing as "trying" to stop, you do or you dont"
he was talking about cigs though, no one knows about the pills, except my med help buddies.
good luck and congradulations
good for you buddy... you lucked out!!!
