I Have Had PTSD For 18 Months. I Am On

I have had PTSD for 18 months. I am on 300 milligrams a day Effexor, Generic Klonopin once day, Generic Xanax as needed. Every time i try and back off with Effexor or Klonopin, I get panic attacks daily, rendering me disabled. But while medicated my main focus is sleeping. I feel exhausted no matter how much good sleep I get, and not motivated to get tthings done. Plus, while I have not had problems coming off Opinion, I hear it is highly addictive. Is there some other drug that works that I do not sleep so much? I slandering g if I can hold a job?
