Thank you for responding! I will try some of your suggestions that I am not already doing. I'm 77 and have had these cramps for years, had them stop and they have now restarted every night after 2 hours' sleep. Then I'm up and down the rest of the night until I just get up. I'm already taking a multitude of supplements but will start with the CoQ10 tonight. My physical therapist has used radio frequency on the nerves which helped some for a day or two, but it is an alternative treatment and not real reliable. I've also tried 3 prescription meds which haven't helped either - painkillers and muscle relaxers. I look forward to a time where insomnia was my only concern at night! Thank you again.
