And so sedatives boost that sleepiness signal. A lot of times with insomnia, what happens because of the excess activation arousal, your sleep signal could be just fine. It's your wake signal that might be too high. And so when someone is taking say a sedative medication, what you're doing is you're just you're trying to drive up that sleepiness signal so high it's just steamrolling over whatever activation you have. And often that may work. And the reason it can work long term sometimes is if you steamroll it over enough, you can you can maybe break that learning.
