Hi, I just did a search on the symptoms you've got because I've got the same thing.
I don't know what's wrong with me. It started toward the end of my vacation (around May 25th or 26th) this year, & it hasn't let up. I'm always SO tired, even if I sleep 10 hours, nauseous, wanting to throw up, either not hungry or SO hungry that I feel as though I'm starving, but when I eat a couple of chips or a cookie or something, I get nauseous again. The same thing goes if I even LOOK at something when I'm not hungry. Then last night, I got cold (uncontrollable teeth chattering, shivering, etc) even though it was at least 60 degrees in my bedroom. & it's starting to get harder for me to sleep since right when I first get in bed, I feel like throwing up. & I can't move much or else I WILL (or feel like I will). This sucks.
Also, my sister also has the very same symptoms I have.
I'm hoping to get a doctor's appointment tomorrow so I can find out what's going on. Does ANYONE have the faintest idea?
