Oh another thing you should be aware of with bupe from the clinic. They can not prescribe you anything less than 8mg daily from what I've seen. Every patient is on 8mg, 16mg, or 24mg. They prescribe you based on the strips and not the milligram dosage. In my experience the best way to deal with them is to take whatever they give you during induction if they want you to dose at the clinic itself. Since you'll get take homes upfront unlike the methadone clinic you can just take whatever you want at home without telling them and stockpile whatever is left over. At the clinic I went to they do not check the amount of bupe in your system when you're drug tested they just look to make sure you're taking bupe and not other drugs like thc, benzos, or whatever else.
Most people I know are given a prescription for 2 weeks worth of whatever dose the clinic gives them. In my case that was 14 8mg strips of bupe. Since I only took 2-4mg daily (I took higher doses back then) this 2 week supply ended up becoming a 4 week supply. This is why bupe is so common on the street now. The majority of people prescribed it are not taking the full dose they're given.
I've gotten my daily dose so low now that one 8mg strip lasts me an entire week. So for every 7 I get from the clinic I get 6 left over.
You'll have to experiment yourself and figure out your own level with bupe. It isn't like methadone. They aren't making you take it in front of them and line up for the tin man. I did not make it with the clinic long. I didn't see the point in spending $400+ a month, pissing in front of people, attending group with junkies, and making the trip into the city every two weeks when I could simply purchase some bupe off the street for cheaper and not have to deal with all the BS they make you go through.
