Pulled 2 days of no sleep in hopes to fall asleep the night before an early flight, STILL CANT SLEEP

Last few times I’ve gone to Vegas, getting on an early flight being so sleep deprived going into an even longer day with the time difference sucks. I still have never been able to fall asleep on the night before or day before a flight. In attempts to fix it this time so I can not feel shitty, I prepared by staying up about 45 hours straight in hopes I’ll be tired enough to get 6-8 hours of sleep before needing to leave for the airport. Still can’t fall asleep. Now I’m gonna starting Vegas on over 3 days of no sleep. 3 days is when I start to feel shitty from lack of sleep. On average I go about 30 hours in between sleeping assuming 6-8 hours of quality of sleep. I’ve been like this since about 13 years old. I don’t even have flight anxiety, I look forward to flying actually. This sub are the only people who understand, no one in my life can even remotely understand how much of a curse this is. Everyone I know can sleep just by laying down for 5 minutes.
