I took 1mg klonopin for 6 months and then withdrew horribly off it. Ew hate the stuff.
Anyway I have taken 1mg Ativan for anxiety attacks combined with Ssri's for over two years with no problem. I never take it more than 2-3 times a week.
It knocks me out though. I ONLY use 1mg for panic attacks. We just added .5 mg daily in the afternoon to knock back the anxiety I get in the afternoon. Works good, just be careful.
