"i&#039;m taking 75 mg qid,or severe spinal degeneration as well as other issues. in the past i used dilaudid, percocet, and m.s. contin. works great for pain but i am more tired than with other drugs. my insurance company denied approval, so i faxed them a letter explaining why i needed it and they approved it 10 minutes after the fax was sent. thank god !!"
