@jakedduck1, Yes, rebound insomnia for me. I was only sleeping 45min - 90min a night for about a 4 week period. It was awful.

I tried several medications at the beginning with the support of my GP. I tried mirtazapine which worked for about a week then the insomnia came back full force. The brain fog on this medication was also substantial for me. I then tried Trazadone, which worked for about a week then nothing, back to insomnia. Doxepin was the next thing we tried and it didn't work at all, it might as well been a placebo. The last thing we tried was gabapentin and thankfully, it worked for me!! Important to note that the above medications do work for some people, just not for me. Gabapentine works decently for me with very few side-effects and NO brain fog.

I'm lucky to have a sleep clinic where I live. I had my first consultation yesterday and I think I'm in good hands. He wants me to continue with gabapentin, he feels that is a good medication for insomnia as it helps to bring on sleep as well as induce deep sleep. For now, he has increased my gabapentin from 600mg to 900mg with the goal of restoring sleep fully. He would like me to get off antihistamines (UNISOM), I take half a tablet currently. Once I learn and get a handle on sleeping techniques like CBT-I, we could then consider reducing the medication. First and foremost is to restore the sleep, no more "white-knuckling". My follow up is at the end of October. He shared that since I was taking clonazepam for the last 20 years, it could take up to 18 months to let the brain rewire itself so I need to be patient. I think this is going to be part 2 of this journey I'm on.

To summarize, I glad I'm off clonazepam, there was an absolute blunting effect that is not entirely perceptible to the person taking the medication and once it is out of your system, it's like having a veil lifted. Pretty remarkable!

Just want to stress these are my experiences only.
