Electrolytes and heart palpitations, racing and high blood pressure

After 5 weeks of chronic diarrhea and just constantly peeing all the water I drink, which was a lot, I finally wound up in the ER completely dehydrated. The doctor recommended Pedialyte. I'll have to double check, but I believe it was up to 4 cups a day. I quickly noticed that whenever I drank it, my heart would settle down and stop racing. I began eating really healthy snacks as my routine diet, which should have been enough to have electrolytes in balance, but they weren't. I kept needing the stuff. I drink 3 cups a day. I've read that you can certainly overdose on it if your body doesn't need it and also that it willaste really salty if you don't need it. I have only experienced that once and it was shocking how awful it tasted. The next day I drank from the same bottle and it tasted fine again, just mildly salty. They say COVID can indeed throw your electrolytes off, so it's something to consider for those of you with heart issues. I don't know if there's a way to check your levels or how long may be too long to supplement this way, but I accidentally discovered that it was helping, so I've been drinking it for 5 months now with no il effects. I get the unsweetened clear one as sugar is not going to help me at all. There's plenty to Google about this, so look into it if your heart has been affected. Also check for adverse reactions to medications. I'm not on any, so I didn't research that.
