Yesterday I started and although I wasn't really hungry, I did want to eat. I do kind of have a headache but it's not too bad. I also feel a little like I'm drunk. Is that weird?

I'm not a big drinker, so is that normal? I plan to go 21 days, but it's hard fooling my hubs that I'm not hungry for that long. He would freak and try to make me eat, but I really want to do this for myself.
