"i just started taking tegretol on june 3 for mood stability. also prescribed celexa on same day. i also take methadone 10mg 4x a day for chronic pain management for last 10 yrs. i love how it makes me feel and it&#039;s very hard for me to get angry but, it interferes with the methadone.  at first nothing except feeling drunk for the first 4-5 days. then it started. withdrawal symptoms, increased pain, restlessness, insomnia, fatigue and nausea. not sure if i can continue treatment but will find out on june 24 after my doctors appointment. also taking meloxicam. will let everyone know my results friday afternoon."
