Broken sleep can become very frustrating.
I used to be helped by clonazepam at night.
On nights I have extra difficulty, I add temazepam once or twice in the night.
When I was mixed, neither worked well.
When I was hypo, temazapam gave me approx. 2 extra hours.
Now temazepam gives me 4-7 hours. I take it if awake at 12 midnight or 2 am.
