Feeling Dizzy and Lightheaded for 24 Hours - Any Remedies?

I normally drink a Propel in the morning. When it's really bad and Propel doesn't help, I do salt shots until I feel better. Normally a half teaspoon of salt and then wait 30 minutes. If I don't feel any better, I'll take another half teaspoon. And then rinse and repeat until I feel better or I've done four to five salt shots. Normally one to two does it, but I've learned the hard way that some days you need to just give up and listen to your body.
