I haven't been feeling well either. Mine's on again - off again thing. I keep going back to the time I was treated for those bugz/mites...just a feeling.
But anyway, what I've been doing is, when I feel pretty decent I'll make just a giant pot of Vegetable soup. The kind with real veggies, V-8 and let it simmer.
Then all I have to do is muster up the energy to grab a bowl of that and it lasts all week.
Little by little AND with a multi-vitamin and Echinacea, I beat it and start adding crackers and build from there.
The Campbell's Chicken and Starz I actually like but add a little bit of real stock or bullion, salt if my throat is sore.
It doesn't really give me that boost though. I have those broth type soups when I've not been able to keep something down. That and a bit of club soda. Ginger ale is just too sweet for me.
Hope you're feeling better and even if you don't feel like it try to nibble on a carrot or cracker, even toast (just a piece).
My husband hasn't been feeling well either. It's just that time of year. Plus I have to remind him to "anti-bacterialize" his hands. He's much more in public than I am
