I've just been to the doctors and after 3 months on fluoxetine my doctor isnt happy that it is having any effect with my depression. He has advised me to stop taking it for a week and then start on mirtazapine. This is an antidepressant i've never heard of and after doing a bit of reading around im still unsure as to what im going to be taking. does anyone have any advice of what this medication is going to be like or any possible side effects......i feel so confused
