"i just started this med yesterday for osteoarthritis &amp; fibromyalgia. after reading the other comments my experience is pretty normal. i&#039;m itching like crazy, had a bad night-no rest, nausea &amp; mild headache. with all those side effects, it appears to have knocked off the edge of the pain. i will continue using if for a few days if i can handle the itching. i want to give it some time because i cannot use narcotics. i end up in the hospital with dehydration from vomiting when i use any narcotics."
