my mom recently went away to a women's rehab for drug addiction such as meth and Klonopin, she was there for about three months, and the people there prescribed her to Suboxone, I always have doubts and think what if she's using again because this morning she woke up and she has to take the pill twice a day one in the morning and one at night, she seemed drowsy and almost high looking and I looked up the side effects and it says drowsiness or a drunk feeling and difficulty concentrating so what I am asking is, should I be worried and has anyone ever been prescribed this drug?
