depression
"I am male aged 55. Suffered from anxiety my entire life. Had been addicted to Ativan 3mg for 30 years. Suffered depression 6 years ago and tried Wellbutrin, Prozac, Lexapro & Buspar. I stopped taking Ativan (on my own) by tapering over 4 months. Then panic attack - fear of heights, and insomnia struck. My doctor prescribed Mirtazapine after hearing my story. Started on 7.5 mg, then 15mg and after 30 days, increased to 30mg. This medicine has worked extremely well for me and that's why I am sharing my story. SSRIs failed. I have been on 30mg for 45 days now and I sleep 8 to 10 hrs, depression gone, and my confidence is back. 
Main side effect is lack of energy during the day and anxiety is not completely gone. Give Mirtazapine a chance."
