Your comment resonates with me because it’s very similar to my story. On lorazepam but my pcp wanted me off it and wasn’t working for sleep anymore. Plus reading about benzos made me understand that taking them long term can wreak havoc with your brain. Cbt-I….exact same experience. Mirtazapine is working for me along with 1 mg melatonin. But after reading what you wrote about melatonin, I’m going to cut back on that. Is sleep perfect every night for me? No, but it’s far superior to what it once was.
