just wondering my doctor started me on fluoxetine. wondering how long it takes for it to start working? for my anxiety and panic attacks? for a month before i was light headed.... faint feeling.... legs gonna give out.... feeling you name it where i was only moving around 30 mins a day. now i am in a week into the fluoxetine and moving more around now and being light headed not as bad... but wondering how long before this stuff really kicks in?
