I have absolutely NO side effects and in addition, I have never felt better in my life!!! I have fibromyalgia and I have taken every known pain medication known to man and nothing has worked for my pain. After taking this drug for just 3 days all of my pain is totally gone and I have more energy than I have had in many years. I hope I can take this for the rest of my life. My husband says he has not seen me do this much in the last 15 years. I don't know what is happening to the rest of you.
