mental energy i mean

i have early stages of diabetes or kidney failure or something like this, for about 18 months now, and carbs do not make me have more energy, at all, they make me feel pretty fucking bad actually, it's mental fog and kidney pain and muscle weakness and depression, in actual fact

no, i've varied all the other parameters in recent times but not adding potassium

i'm suffering from potassium deficiency, and probably other electrolytes related to the kidney problems, i get cramps, the potassium is massively reducing this problem though, i'm almost starting to feel like my old self again
