Hi
@Flamingo74
Sorry to hear about your tummy problems. Never fun, but especially when away from home.
If you’re only taking metformin and no other diabetes medication then not eating shouldn’t be a problem at all. If you’re not hungry then there’s no need to eat. Plenty of fluids, with some salt added will be important though.
Your higher than normal reading could well be because you’re under the weather, or it could just be one of those inexplicable diabetes moments. It’s not a terribly high number in the scheme of things (I know that’s all relative to your own ‘normal’ and targets) and will hopefully be a temporary blip.
Hope you feel better soon.
