I am currently taking 5mg prozac, will go up to 10mg on Wed after a week, but have no appetite. Having panics and feel sleepy and nervous, but i am sticking with it, because i lost 4 pounds or maybe 5 in 4 days. That is the only thing so far i like about this medicine. Just wonder if when start taking the higher dose the appetite will be even less and if the panics will go away. Thanks.
