Cramp / Cramps / Cramping

this is why they invented Gatorade. it restores your electrolytes. drink it, it is good.

if you're really electrolyte deficient, you could try mixing some of the gastro powder (not sure of brandname, gastrolyte??) that you can get from pharmacies for when you suffer diarrhoea. you mix it with water and it's designed to quickly fix dehydration and electrolyte loss.

Dioralyte is the brand name I've seen.

The purple one tastes like shit. I'd rather just put up with the salty taste than disguise it with 400 tonnes of artificial blackcurrant flavour. Not sure what other options are available but I'd avoid that one.
