Salt stick capsules the ones without caffeine. Amazon has them. May not help much right now but it would be good to have on hand. They're like $25 for the bottle but it's huge and lasts a good while. I take them daily and it takes 3 months for me to get through it. For now I would get spaghettios with meatballs and chug powerade.

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.
