Sorry to hear you are feeling so ill!
All the usual BRAT recommendations
https://en.wikipedia.org/wiki/BRAT_diet aren't very helpful for T2s. I mean, keeping bg low when ill is one of the best things we can do to help our bodies to heal.
So nowadays (and as the veteran of a couple of bouts of Norovirus over the last 10 years), I heartily recommend Chicken Soup.
It is, after all, the universal panacea
Depending on how ill you feel, and how much your husband is willing to pamper you, there are a whole range of options,
- chicken broth, which is just a stock cube in a mug with boiling water
- real chicken broth made with real chicken stock
- broth with diced chicken in it
- broth with diced chicken and veg in it
- broth with an entire roast chicken dinner + a knob of butter, blended into it with a hand held stick blender
I usually start with the broth option and work my way back up to solid food.
If you decide to go the tinned chicken soup route, then keep an eye on the carbs, but Campbells Cream of Chicken has approx 7g carbs/100 g, which most low carbers can tolerate, especially when recovering from a near death experience!
Hope you feel better soon.
