Learn on my mistakes. 16mg of bupe is a lot. But some people need it, that is the consensus on here. But the sad truth is that bupe is a very addictive substance. If u stay on it longer u'll have hellish w/d. Let's say u're on bupe for 10 months like I was, then wanted to come off 1-2mg, u'll have w/d for 8-9 days plus RSL and insomnia for 2-3 more weeks. The shorter u r on this drug the better. I actually couldn't handle the pain and duration of bupe w/d. I tried. Got to like day 5 then broke down and went back to the doc. Then I used heroin for 2 days to get the sub outta my system, did w/d for like 24 hrs, then took like 0.25mg of bupe twice and pretty much had no w/d at all. Just the RSL and jumpy legs at night and the weird feeling in the hands and feet(burning, tingling, etc). Valium, clonidine, vitamins, exercise and neurontin took care of that, plus some seroquel and ambien which I haven't used yet but might if needed.
Sub is great for elevating cravings. I'm off the sub now, has been about 1.5 week and when I wake up in the morning I think of heroin. Hopefully that will subside soon, but having a drug free brain is odd, when one has been on opiates for as long as me(9months heroin, 9 months sub).
Some people just need to be on sub longer but the longer u r on it the harder it will be to stop. Even coming off like 0.25mg u'll have some w/d, then RSL and insomnia for 2-3 more weeks. So I suggest staying on it for as short as possible. Bu if ur cravings are bad then stay on it cuz at least u r nor risking a criminal record and all the bad that comes with illegal drugs.
But that being said, sub is still a biach to come of off if u've been on it for longer than 2 weeks.
