I hope you are feeling better by now- I would suggest that you stay as hydrated as possible esp with the vomiting. Can you drink ginger tea? ginger ale (diet)? Ginger always calms down my stomach. Chamomile calms down the intestine and peppermint does too. I can only drink them when I'm sick. How about yogurt? If you get the low carb type, you 'd get some protein and probiotics.
That's what I did the last time I was sick- if it's any consolation to you- I took my medicine- but lost it before it had the chance to doo any good
My BG did go up- but started to come down again as soon as I was able to hydrate and eat my yogurt.
I just want to live happily ever after-every now and then. Jimmy Buffett
