What have you tried that had no effect at all?

I started having insomnia in 1980 when id go 2, 3, or 4 days without any sleep. My first treatment was from a hypnotist who waited my time and money. Since then I have every prescription drug(Ambien, Lunestra, etc) Ive even tried the 3 new drugs (Belsomra, Davigo, Quivvic). They all might as well be placebo. I tried red light therapy, Vagus nerve stimulator device, blue light blocking glasses, some handheld device. Ive also tried every Supplement and tea. CBD gummies and cannibus. The only thing that ever helped was Propofol after a colonoscopy.For me, nothing ive taken over the years has helped me even a little. I now average 2 to 3 hours a night but only if I'm lucky. I go at least 2 days a week wirh zero sleep. But I am living proof that insomnia in the form I have is not fatal, just makes life harder than most people who sleep every night could ever understand.
