Fatigue is worse

Is it just me or is the fatigue getting worse? I thought once I got adjusted and through the first couple weeks I'd at least be acclimated to the feeling and maybe be able to muster up some energy but I swear it's getting worse. Slept on my lunch break and it's now 2 and I can barely keep my eyes open. I went home early because of this yesterday. I'm so afraid I'm going to be too tired to drive or something!
