i went to the doctors today and she put me on fluoxetine for my depression, i took one today and felt abit happier but felt abit light headed and dizzy later on at night, but i am going on holiday in 2 days time and i have read that you start having side affects after the first week up until the 4-5 week.

is this true ? and what side affects would i experience as i dont want to spend all holiday feeling crap

im 17 if that makes any difference
