Are you a Type II- diabetic? Night cramps seem to appear in diabetics when their metabolism is not well adjusted. Did you let check your A1C?
Not diabetic. Wore GCM multiple times. Did A1C and insulin tests. My body just doens't like carbs.
My cramps weren't night cramps, but sport/exercise cramps.
All carbs, or grasses?
Fun fact - Low magnesium can contribute to type II diabetes. It’s been found certain people not responding to improved diet and medication have the A1C drop after starting mg. Of course, if low Mg isn’t a factor then supplementation will do squat.
Cramps can come from Calcium and Potassium too.
Or excessive creatine consumption. Also, sleep disturbance.
