Not hungry/funny taste in mouth

I haven't really been hungry lately. Well, I guess a better description is that I don't want food. I eat, but nothing tastes good. And, I have a lingering taste in my mouth. It tastes sweet all the time, and my throat has a dull sensation. I don't know what the deal is. It doesn't matter what I eat... it just isn't satisfying, I can't shake this strange aftertaste or sweet taste. I haven't wanted anything except AO. This has kind of gotten worse, but it started around Easter when I went to Illinois to visit family. I didn't really get the things I wanted to eat, and had to drink a lot of shakes. When I got home, I was just turned off by them, and still not too keen on food. Anybody got any ideas, suggestions? Do you ever feel like this?

Mmmmmmm. Have you checked your blood sugar? I have had the strange sweet aftertaste thing happen. Usually, my blood sugar would be up a bit. All I want when I get like that is cottage cheese. I can't stand to put anything sweet into my mouth. Mine only lasts for a day or two though.
