"i was on 40mg of citalopram which was working a treat but wasn&#039;t sleeping so i was given mirtazapine 15mg. i&#039;ve been on them less than 2 weeks now and the change in myself is simply terrible. the first couple of nights i got an amazing sleep but found it hard to get up in the morning but things have just gone from bad to worse, i have bad anxiety, can&#039;t sleep, feel like a walking zombie, dizziness is terrible, crazy dreams/mares, compulsive sweating, itching/burning sensations and the worst for me is my anger it&#039;s unexplainable i can fly of the handle for someone looking at me. this drug might work for some people but i&#039;d say avoid at all costs i&#039;ve never felt so unhappy and down right miserable."
