I’ve recently weaned off temazepam. I was taking 30mg for a number of years, and like you, it wasn’t really working well. My new doctor had me decrease to 15 mg for a couple of months and then to 7.5 mg. I was also prescribed nortriptiline - as my doctor thought I could change to it. The nortriptiline caused heart palpitations so I stopped it, but continued to wean off the temazepam. I’m now off of both. Sleep is still not ideal, but somewhat better.
