Avoiding sleep

Anyone else here avoid sleeping sometimes even though you’re exhausted? I go through cycles where I sleep well 8+ hours and I go through cycles where I get less than 7 hours and I swear I just as tired at both ends of sleep. I attribute a lot of that to my ability to remember to drink water which also cycles from decent to horrible. This week is insane at work with a huge change over of a system we’ve been working on since November. We “go-live” on Monday and it’s been so chaotic at work (in a good way) but I get home and I don’t want to sleep. I know sleep hygiene is important but man alive I can’t do anything about this right now.
