I do understand how awful those leg cramps can be, for me it was not nightly but when they did hit it was bad. I started taking magnesium and Iron and it helped me. I still get foot cramps sometimes but nothing like what it used to be. I cant remember the last time it went into the calves. I also have acid reflux and take Prilosec for it, for me going off the Prilosec is not an option because a few days without it and I am in incredible pain. Worse even than the leg cramps for me.
I have taken diazapam for a long time to be able to sleep but I didn't notice that it ever helped the leg cramps. Maybe it was a combination of both the diazapam and the magnesium all I know is that I very seldom get woke up anymore by the cramps.
I wish you the best and hope you continue to talk with us here in the forum.
