hi,i had a lower spinal surgery in 2010 and was put on pain pills,by 2015 i was put on pain control because it was a failed surgery,that said i was prescribed buprenorphine 2mg 3x per day,so i discontinue using this medication by slowly dropping 1mg per every two months,i'm down to 1/2 mg for the last 3 months,reached my last dose on 8/11/16,but i'm having problems sleeping,maybe 2 hours every other night! i'm wondering will this ever level out so i reach 8 hours sleep per night! really i'm so tired now,ready to throw in the towel,seems this medication is giving me more pain as i withdrawing from it! will i feel normal any time soon!could you please give some kind of time frame,thank you any help you may have.
