I get this too during chelation/detox! In particular gut/colon detox makes very emotional due to draining of electrolytes (coffee enema, Bentonite clay, Xymogen's Opticleanse GHI, etc), and also very fatigued with heart beat faster when I wake up (Enterosgel, Quicksilver IMD, Opticleanse GHI, RestorX, etc)
I am trying to find out why this is also. Maybe I need to take L-Ornithine to regenerate muscle tissue???
