I have been on a few different types of ssri anti depressants through out the years. The ssri anti depressants I have been on were really good at relieving my anxiety and depression. But I got a few really annoying side effects the entire time I was on these ssri anti depressants. I was thinking about trying the anti depressant mirtazapine to help me cope with anxiety and depression and I have heard this has a lower chance of causing these annoying side effects than the ssri's do. Is mirtazapine a good anti depressant to help treat anxiety and depression? Also a few other things that are worrying me about it is I am already a fairly big eater and sleeper. I really enjoy my food and like my sleep. Is mirtazapine likely to make me eat far too much and gain weight? and is it likely to make me sleepy and sleep too often?
