You are a very serious person, my friend.
I just don't sleep because I'm an insomniac who withdraws from weed, beer and benzos.
I usually like sleep a lot. 
Ya know, it's weird, whenever I smoke weed regularly, I don't remember my dreams at all, but then if I stop for even a day or two, my dreams come back all vivid-like and shiz. I've read of this happening with other people, too. But yeah, it's a bitch falling asleep if you're used to either of those three things and then don't have any. For instance, I had no weed or drinks last night, and I didn't sleep a wink. I mean, I was also on opiates... can't sleep on those for some reason... but I would've still only gotten very minimal sleep if it weren't for that, I'm sure. Especially once you get used to hitting the bar most nights and taking shots of Fireball alternated with tall beers, then you just get home, collapse on the bad (in my case, with my contacts still in, which always makes my hangover like 5x worse, for real, because of all the gunk my eyes make when I do that), and are instantly out cold. Getting used to that and then dramatically cutting back the drinking and almost entirely eliminating going to the bar causes sleep to be so difficult to attain. Just never feel tired, and I don't go to bed if I still feel awake.. That and then I ran out of weed the other day and have gotten D's and dope since then but not anymore bud....
But yeah, NOW, right fucking NOW, last night's sleep deprivation wants to catch up with me all at once. Probably from taking my morning dose of Xanax XR and Gabapentin. I didn't take my Vyvanse yesterday, so I might take a second one today. Like damn, all of a sudden I just want sleep so bad. Probably added to me not being tired, having not taken either of those former two since way early the day before. If I take my last dose of those two at like 5PM, I wake up at like 6 in the morning covered in sweat and feeling ridiculous (in a bad way), hit the bathroom, drink some water if there's some upstairs (when I was still at my aunt's, which changed yesterday). Don't feel normal until I take 'em and they have a little time to kick in. Throw in a nasty hangover on top of it, plus mucus buildup in my sinuses from sleeping with contacts in, and I wake up like straight Death some days.
What were we even talking about again? Fucking sleep deprivation plus opiates plus amphetamine. Gets me rambling walls of text about I don't even remember already, apparently.
