Buprenorphine / naloxone
"To anyone looking to get on Suboxone to overcome opiate addiction -  DO IT!!  I've been on Suboxone for 15 months now & have gone from 20mg to 2 mgs literally painlessly. The first time I took it I knew within an hr I had found what I needed to get that damn monkey off my back. A slow yet STEADY taper is important.  There's no reason a person can't easily drop 2mgs a mo. down to about 4mg. If it's making you sleepy, time to taper! It gets a bit slower once you get lower but still not hard at all. Once you get to about 3mg you almost have an awakening!  You get more energy,  and start to LOVE music and conversation again.  I would say that those are the biggest side effects - sleepiness (taper!), and slight emotional dullness."
