No powerade is better less sugar n has b6,b3,b12
Gatorade is your go to! And water!
I had that same issue, doctor told me fluids are way more important than eating, because you don't want to get dehydrated. If you can't keep liquids down call your doctor and go to the er for fluid IVs.
You should probably go to the doctor, you dont want to get dehydrated. And sip on some water, like not even a mouth full, that's what I had to do. Hope you get feeling better!!
