I will give the same advice I have over the past year.

When sick, take care of yourself and don't worry so much about high/low carb. Normally when we are ill, nothing tastes, smells or looks good to eat, therefore eat anything you can get down.

Once you are feeling better go back to low carbing. You have to realize this isn't a short term project, it's for life and 1 week or two here or there taking in carbs isn't going to kill you

I hope you get to feeling better soon.
