She has parkinson disease for 2 years. Had a major back surgery and is in pain since. Back surgeon cant explain why. They recommend her taking vicodin. Vicodin makes her more off balance. I cant trust her with pain meds. She has shown signs of addictive behavior. Ive been able to get her off of it but just last night i caught her taking Lyrica without my permission and lied to me that she didnt take it and that she doesnt know how it got into the drawer. Im losing my mind over this. I had this lyrica in ny cabinet upstairs in my room. My mom would have had to climb a flight of stairs to get to it. She is a compulsive liar with a drug addiction and im losing my mind over it. I dont like liars and drugs. She shared her vicodins with her brother and grandson in the past. Im so disgusted! I dont know what to do next!!!!help?
