I've been on heroin for 5 years off and on. This time I've been using 7 months straight and was up to 1.5 grams per day. I went to a hospital to detox and left within 24 hours bc the suboxine wasn't working but it was making me throw up like my body was rejecting it... So within the last 3 days I have wheind myself down a lot but I bought some generic subutex on the street hoping to find something to kick my habit... But I need to know when like how many hours to wait? Do I just wait until I'm in withdrawal??Also how many milligrams are suggested?
