I am waking during the night with horrible cramps and spasms in areas I don't normally get cramps. It sometimes happens during the day as well. Eg. Top of foot, back, stomach, behind knee etc. I also get them in my legs and toes. But I am getting them more frequently now than I ever did. I am sure my body is lacking something. I am drinking lots of Water and taking my Vitamins. I am also taking extra magnesium citrate. I am on day 7 of my pre op diet. Just want to know if anyone else is experiencing this?
