I take klonopin (1mg) at bedtime to help me sleep, after going through a laundry list of other meds for sleep that just didn't work. I also take it PRN during the day, but most days I don't need it since I added buspar. I'm trying to get off of it though and really only use it PRN, and my pdoc is on board with that, although she'd be okay with continuing to prescribe it for sleep too. But we just added Seroquel to help me sleep and so far, so good. If things keep going well, when I see my pdoc next week I'll talk to her about halving my klonopin.
