Help with electrolyte drinks

So Ive been attempting to fast for a while now, just got back into it. The hunger obviously sucks and for some reason it doesnt leave after a few days but whatever (maybe its cuz I watch youtube videos containing food, or maybe the few psych meds and the single vitamin is messing it up idk). But the big problem that inevitably causes me to end the fast earlier is the electrolyte drinks. Trying to intake the potassium, sodium, and eventually magnesium + calcium makes me feel ill. Its not the taste its the physical feeling of it in my stomach. It makes me feel sick. What are some alternatives? Cant I just have a bit less sodium? I think I could handle that.
