My hunger kind of comes and goes- for a few days I feel like I'm starving and could eat everything in the house, and then a few days I just don't feel like eating anything at all. I don't know, seems ok to me- my appetite always eventually comes back. This has been going on for weeks.
Re: Blah
That did it for me a couple weeks ago. Ended up having a sinus infection. I wouldn't be concerned.
