That is very interesting and helpful! My primary care doctor prescribed 15mg, but my psychiatrist (who I no longer see) had suggested 7.5, so I cut the pill in half. I'm glad to know it works at even lower levels if I need to do that. I am currently on 0.125mg of Klonopin down from 1-1/2mg 7 months ago. I don't think it is doing anything at this level but feel I need a bit more time to go to 0. I will be glad for that. And I desperately needed something for sleep so I hope this does the trick. I slept great last night and not at all the night before. I was prescribed Klonopin in 2012 for insomnia and night sweats. It was my bedtime friend for a long time but I did not realize the hold it had on my brain. I cheering everyone on as we taper off and allow our brains to heal!
