I have neuropathy in my feet and used to suffer from leg cramping at night and sometimes during the day. My podiatrist recommended drinking a small glass of tonic water before retiring to bed. I have followed this routine and no longer get leg cramping. If it worked for me, it may work for you.

Drink as much water as you can stand. 😀

Yes I myself suffer from this cramps !working out the hamstrings and quads helps a lot.
