When I had it before (end of 2020, beginning of 2021) I ended up in the ER twice and got admitted for an overnight due to dehydration and very low potassium. So I'm just trying to stay hydrated and I am taking a potassium supplement. I thought I had eaten something bad and it had run its course through the night bc I seemed better during the day today. I did eat through the day, lightly, (pudding, soup, crackers, clear liquids) but now at bedtime it seems to be starting up again. That's why I'm wondering if it could be Covid. Seems like if it was food poisoning I would have been sick all day. Idk. It's weird. No fever. I do ache though, esp guts.
