Usually for me it's because my thoughts are all over the place and I can't turn my brain off. When I notice it happening, I get up, stretch for a couple minutes, drink a glass of water, then take a marijuana edible or a couple hits off my vape. Then I lay back down and put a blindfold on, knocks me right out. I try to get my dosage right so it's either "relaxed" or "vibing" but not like, incredibly stoned or anything
