"my rheumatologist feels that this medication allows me to sleep without extreme night time pain. if i do not get sleep, i am unable to function during the day. this medicine allows me to sleep without pain causing tears every time i turn over. sorry, i have had none of the side affects except for the ability to sleep for 8 hours---the reason i agreed to take this medication. quality of life trumps pain and the chance that i will have any of these side effects.
