Sleep problem, is this what's going on?

[I spent the winter writing songs about getting better]

The last six months thanks to some shakeups at work, I ended up with a (for me) absolutely hellish schedule that required me to get up way earlier than I'm used to. Plenty wouldn't mind or would even like it, but I'm not a morning person. Mercifully this ended last week and I now have a schedule where I don't have to go in until 11:30AM, and I was able to catch up on sleep. However I'm still feeling tired a lot, even after 8 hours. I have a theory that I racked up too much of a sleep defecit the last six months and it's going to take awhile to even out. Even during that time I was sleeping in quite a bit on weekends but wasn't feeling fully awake or refreshed, then there was my little Chicago trip. So is this something where I'll have to just adjust over the next couple weeks instead of just sleeping in a little bit now?
