Mirtazipine has been a miracle drug for me, I am pretty drug resistant but this one got rif of my depression and panic disorder very quickly. Remember there are quite often side effects in the first few weeks but they disappear overtime. The one thing I will say about the first four weeks of taking it was that I had strong suicidal ideations brought on by the drug, but they passed as well. Now I wouldnt be without my mirtazapine for all the tea in China.
