My husband had them all the time when he was on Lipitor. He would jump out of bed, waking me up, and try to stretch out the cramps. He has not had them since he stopped taking Lipitor more than 18 months ago.
Yes, I also would jump out of bed with severe leg cramps while I was taking Lipitor.....but only in the final year that I was able to take Lipitor. When I stopped Lipitor due to muscle problems and weakness...plus fatigue-the night time leg cramps stopped. I never really thought about them being related at the time.
