I have alot of muscle cramping especially at night and I tried to take calcium and mag. but my stomach feels like i have acid indigestion and the metal taste in my mouth gets way worse. I also get feeling very depressed which normally i don't feel like that. I know i need both cal. and mag. because i eat nodairy products, no gluten and limited fruit. I have tried mag. gylcinate liquid mag and also mag. injections they all upset my stomach and depress me . If anyone has any suggestions i would really appreciate it. I will be getting my fillings out October and i hope this mght help but am worried it won't.
