Also try fresh ginger. You can get ginger bits with sugar like in the Asian restaurants in stores. Or shred ginger onto food or in smoothies. Note: some ginger powder has additives to make it pour better.
i found probiotics, Vitamin D, and manganese helpful.
Prescription for zofran. Don’t eat what I’m allergic to. Tums and allergy meds
I also use zofran when my stomach won’t calm. I am now taking probiotics and am a firm believer in them! I usually try cold icy fruit first and always eat soft foods in case it comes back up.
I use digestive enzymes when I need to eat but don't feel up to it. A heating pad also helps when my stomach is upset.
