Thanks everyone for well meaning words. But as some of you mentioned if what I am doing works for getting rid of cramps ,then great, just great. I certainly tried a lot of things and now I am quite happy with 100g of carbs and no cramps as a result.
It is a pleasure to wake up in the morning and do a luxurious stretch without activating some muscle that immediately goes into spasm or even change a position in the night without the same happening. Not to speak of jumping up in the middle of the night when I am being stuck with red hot poker and being sore for a couple of days.
