that's exactly how i am when i'm sick. this is the best thing to help me. i make a bunch of green tea with lemon. sweetener if you need it. it won't need much.
drink a ton of that really hot. seems to really help open the sinuses. and help with sore throat.
mint tea is also really good, helps w/ tummy and throat.
or try mouthwash, brushing teeth more often. when i get that nasty taste out of my mouth, then the cravings are better or gone.
ginger tea might also be good.
and of course using a million tissues, and lots of showers/baths to help with the congestion and sore muscles.
oh and one of the best things to make, is lentil or minestrone soup. beans keep you satisfied for a long time. gives lots of energy. lots of iron and veggies.
hope that helps
