"was put on 30mg. all was ok... at night got a good sleep... for maybe the first 8-10 days but depression returned as soon as i woke in the morning. after the first initial 8-10 days it stopped working altogether. my doctor told me this might happen..but to ride the storm for another two weeks as sometimes it takes your body a while to adjust. after 4 weeks went back to the docs he put me on 45mg. been doing that two weeks now and it still doesn&#039;t work. in fact i feel just as bad if not worse than i did before i started it. i&#039;ve seen other reviews about mirtazapine where it really works for some people and others it just doesn&#039;t. don&#039;t think i&#039;ll take anymore, side effects ain&#039;t worth it."
