I too had absolutely no appetite on prozac - it was even hard to force myself to eat. It took 8 days after quitting it for my appetite to come back. I still get dizzy and have some other lingering side effects though after 2 weeks off.
I believe Prozac breaks down into an active metabolite norfluoxetine with some other nonactive metabolites. I've read it takes around 7 days for half of norfluoxetine to be eliminated - so 1/4 left after 14 days etc, plus whatever amount of fluoxetine that hasn't broken down. Of course we all break these things down at slightly diff rates. I'd give it 3 weeks personally.

Thanks for all your replies. I too have been reading up on this and Prozac takes quite a while to leave the body. it's been about 12 days and side effects are not as bad as the first couple of days, but some are still lingering. I can feel them slowly deteriorating which is good. I guess I'm just impatient. I wanted everything to happen right away, and unfortunately it doesn't happen that way! I want my appetite back, the nausea to completely go away, and for the increased anxiety to go back to where it was before I started this drug! Well, thanks for listening to me rant!
