Hi iam on day 4 of my subutex detox, I dropped from 8mg to 6mg, but felt crappy and anxious, so dropped 0. 4 weekly. Last tab was tuesday. How long will my insommnia last? I am down to my last sleeping pill. Doc gave me a 7 day supply, but had to double up as I did not work. Any info or help would be much appreciated. ALSO HAS ANYONE ELSE LOST WEIGHT DURING DETOX, IVE LOST 42LBS.
