"this drug worked very well after my shoulder surgery. i took it for 6 weeks. my doses started at two every 6 hours for one week and tapered down to 2 at night. i was never told and did not realize that withdrawal would be a problem. i had several of the common withdrawal symptoms and 10 days after stopping the drug completely, i still have insomnia, night sweats and anxiety. no other sleep aids help me sleep yet."
