Hi,
I have cramps too, mostly when I go to the bathroom. Saw my doc yesterday and had barely explained about them before he was writing me a prescription for an anti-spasmotic medication called levsin. I haven't filled it yet, so I can't comment on it's effectiveness, but if you call your doctor there is medication available for cramps.
btw, the reason I haven't filled the rx yet is because it supposed to cause dry mouth and tiredness and I can't decide if the cure is worse than the disease.
