Hi,
I suffer from extremely painful cramps in my legs and toes. To the point where i scream with pain.
But, my other half asked the Midwife on what to do and she said drink Tonic Water an hour or so before you go to bed.
The Tonic Water has "Quinine" and this stops the cramps.
Since drinking the tonic water with quinine i have no longer had any cramps apart from when i forget to drink some...then i suffer the painful cramps again.
So, drink Tonic Water (plain or Bitter lemon flavour) and it should stop.
