Remeron
"This has been a lifesaver for me for anxiety and insomnia.  I was on Zoloft 75mg for the last 5 months and it was of little benefit.  I've only been on 7.5 mg of Remeron for 7 days but the results have been great, (still also on 75mg of Zoloft). Remeron gives me a good 8-9 hours of sleep every day, a strong appetite (I lost 25 pounds in 5 months when I began to have these problems).  My energy level is returning to normal.  90% of my anxiety is gone.  It is nothing short of a miracle.  Yes, I feel a bit groggy & dopey for an hour or two after I wake up but that is a small price to pay for me getting my life back."
