"for me it has worked great. at first when i felt a panic attack coming on i took .5mg as soon as i felt it coming on and within 5-10 min i felt incredibly better. after about 3-4 months i was up to 1mg daily at most. it seemed to lose effectiveness after about 5 months so my dr has tried other medications and weened me off the klonopin. after several months of trial and error (guinea-pigging) i asked the dr to put me back on the klonopin and it has since worked great again. ive been back on it for about a month now. hope it continues to work. i rated a 9/10 only because it lost effectiveness for awhile."
