Which electrolyte?

So I'm embarking on a quest to fast for.. well we'll see, hopefully I can pull off 48 hours at least. But who knows. heard it gets easier after 2 days so maybe 5.

Goal is all the health benefits YouTubers are talking about and self discipline.

I'm Currently on hour 15 aaand. Morning hunger mostly passed, having a light headache but idk if that's related.

Anyway, what do you guys recommend in terms of electrolytes?

Putting plain salt in water is plain disgusting lol.

My first instinct was to run to Costco and grab some LMNT but everyone is talking about how terrible that stuff is.

what do you take during your fasts?

Any other tips would also be appreciated!
