Do any of get cramps in your extremities? I was talking to my cousin who has MCTD and Fibro and she ask asked me this question. I sure did and it would send me shooting out of bed that was until i started taking 50mg of potassium before I'd go to bed with no problems since. I was told to up it to 100mg today as it was still reading low after taking 50mg 4hrs prior to my blood work. I would get it really bad at work in the 120 degree heat of the engine room of the ships hands feet legs and arms.
Just thought this might help someone that's having problems with this.
