I will tell you what truly knocked me out after 3 days no sleep I went Ip and still was awake another 2 until we tried Thorazine , 50 mg and I slept like a baby for 14 hours.

It’s my last ditch prn if I go more than 5 days without sleep or even a few hours a night. Only side effect is a hangover the next day.

Maybe your Pdoc will consider thinking outside the box for a prn that likely knock you out.

I so hope you get some decent sleep soon I worry about you
