Buprenorphine
"I have been on Suboxone (Buprenorphine) now for 6 months. I was put on this drug to come off  loratabs which I'd been taking for years. This miracle pill took care of any cravings for loratab and at the same time, took care of my pain (a few herniated neck discs.) I did experience side affects but the good out-weighed the bad so I stayed on the Suboxone until now. The only real side affect I can't seem to stand anymore is: excessive sleepiness while sitting still."
