I've been suffering with insomnia for about a year. Some nights I'm too awake to even go to bed. Mostly I was trying to function on 2 hours sleep. i mostly didn't feel tired but it would build up until I was terrible suddenly. I asked chatgpt because I was getting desperate. Interestingly chatgpt suggested something called a melatonin reset. It also suggested a very low dose of melatonin because it said higher doses (2mg and up) can be counterproductive, which I also found interesting. Anyway, I've started this melatonin reset as it suggested, been doing it about 4 days and at first it just helped me fall asleep, but I kept waking every few hours and wide awake at 3am, but last night I fell asleep at the time I'd wanted (11pm) and woke at 5.30am so huge improvement. I was sceptical before I tried it, and its early days, but I'm impressed because until then the only thing that worked was exhaustion plus co-codamol at the normal dose plus mild overdoses of cetirizine and melatonin. I'd previously tried all the sleep hygiene thing with dark, no sounds etc but although I dim the lights for a few hours before bed and don't look at screens during that time, I've found I sleep better with a talk show on very low on the radio and a reddish coloured nightlight. And a soft toy. Just my thoughts and experience though. I've never tried sleeping pills (I wouldn't count melatonin as a sleeping pill) because as I understand they make you fall asleep but your quality of sleep is terrible so what's the point.
propofol. It's an anaesthetic drug but it's very short acting and stings like a bitch, even if its injected iv.
I thought that too but recently been trying a "melatonin reset" and it seems to be working, which I never expected.
