I have been on pramipexole for quite awhile. It is not working anymore. I have to take 2 mg one around 6 pm and then another around 9 pm. I do not get much sleep anymore. When I am awake in the middle of the night I eat like I have not ate in days. I can't stop myself. I read in the side effects of this drug is excessive eating. I have gained 30 pounds. What can I do.
