This goes for most substances I have taken. I've noticed that if they are consumed during the day and have worn off by night time, and I can get a good amount of sleep in afterwards then this pretty much counteracts any negative feelings I have the following days. Especially if I am able to eat slightly before sleep and more afterwards.
I also suffer from insomnia and have found the feeling of being awake 30+ hours with only a few hours sleep behind you, followed by another couple of hours then being awake again etc to make me feel as awful as any come down.
Don't get me wrong, that isn't to say that substances aren't responsible for some of the bad feelings. But I think that the lack of sleep (and nutrition) simply adds insult to injury.
