thanks heaps capt H...so u reckon it's ok for me to sub it even when i'm doing diazepam 20-40mg daily??
It varies between people. If you have pre-existing medical conditions which concern your heart, your lungs, etc, I would reconsider.
If you don't get heavy sedation or breathing suppression from the dose of diazepam (ie you have a tolerance), then you should be fine.
I saw someone take 20mg of lorazepam (5x the strength of diazepam) on buprenorphine, at least 10 times the amount you'd get from taking 1 pill. He was OK, but he has a HUGE benzo tolerance.
If you can take 20mg of diazepam in a day (four of the 5mg pills, or two of the 10mg pills) and you don't feel much different, then youll be OK to do the buprenorphine.
If you have a very low benzo tolerance, and then decide it's going to be really fun to do 20mg of xanax and then do a lot of buprenorphine, then no, that's a horrible idea.
But 20mg of diazepam is a pretty low dose, I'm sure you'd be fine. However, there's really heavy synergism between buprenorphine and benzos. You might want to take maybe 5mg of diazepam and then do the buprenorphine, and then do more diazepam as you feel necessary.
I take 2mg of buprenorphine a day (sometimes 3mg) and I took 0.5mg of xanax today...I'm pretty high from it still. I dosed about 7, maybe 8 hours ago.
I don't have a benzo tolerance at all though.
If you start at 5mg (or 10mg) of diazepam and then dose the buprenorphine, you should be fine, and could probably take another 10mg of diazepam comfortably and still be OK.
