I'm sorry to hear that
@Kaz261!
I'm not sure, only water, I would have assumed.
If you have one of those sachets for your youngsters, have a read of the pharmaceutical leaflet and contents. There may be some sugars, just as a short term boost as there is in most meds. My endo, said to only take paracetamol, but I dot think that is applicable here.
Yes, do look after yourself, only in an emergency would I have anything that is liable to kick off the hypos.
I would take little pieces of food, and I mean little, to get you back to eating properly.
I would drink copious amounts of water or tea/coffee, unless the caffeine is bad for you.
I would like you to add your own experience of what happens when one of us has been as ill as you sound, so you can use that knowledge for others who find themselves in the same predicament.
Hope you are feeling better soon. (And the kids, of course!)
