Other than this it was a wonder drug for me, I functioned quite well, able to do most anything, work, ski ect. After 10 years it caused my
blood pressure to go too
low, so had to switch to Flexeril 10 mg at bedtime. It also has worked well up until now, my body has gotten too used to it so I am not sleeping well now and it is not helping with the pain, but had no weight gain or bad side effects for all those years. Would definitely recommend this drug for Fybro sufferers! Hope this helps!
