A few years in, I found a psychiatrist who was willing to experiment and we discovered that the two meds above helped tremendously with the insomnia. I was then getting a solid eight hours most nights. There were side effects but they were much better than suffering with the insomnia was.
Now, after a decade, the insomnia seems to be completely gone. Knowing that I have medications available to me that can help me get to sleep is enough that I think I don't actually need the medications any more. So I'm very slowly going off of them. Klonopin first. There are, as far as I know, no guidelines for how to do this. I tried cold turkey, but the side effects from that were fairly severe. So I started tapering. I'm now down to half my original dose. If things go well, within four months I'll be off the Klonopin for good, and then I'll start on the Remeron.
These medications are not easy to stop taking.
