The half life of buprenorphine is at most 42 hours, so there might be some residual drug in your body, depending on your metabolic rate for as long as 9 days.
Let me say how proud I am of you for quitting and I hope your pregnancy procedes well.
I don't feel like complete crap just extremely tired and lack of energy how long will this last till I start feeling my self again?? And being pregnant on top of this don't really help just want to feel normal again :(
This may last for quite a while, and since you are pregnant there isn't much you can do about it. Plus the pregnancy itself can cause you bu feel tired and out of energy, so you may not feel "normal" again for a while yet. But just think about that beautiful baby growing inside if you and it all becomes worthwhile. Eat healthy, stay hydrated, try to do some walking every day. Good luck to you and stay well.
