I also went through a stage of cramps which was very ouchy but then I started getting bad heartburn so started taking Rennie and the cramps eased up. Not sure if it was coincidence or the magnesium in the tablets but I haven't had a major cramp for months. Every now and then I will feel a niggle and stretch my leg out to stop it or give it a massage.

I hope they ease for you soon. You can feel the cramp for days when it is major.
