i have thought about it, and it's not a bad idea. there haven't been any recent drastic changes, i don't hate my job, i'm not recovering from an illness- i'm fine. i just sometimes let my sleep schedule get out of control, and have a hard time getting it back under control. at least for the moment, i'm looking for a short term solution (or at least something more short term than scheduling a doctor's appointment). it's not a bad idea, though, it's something i've been thinking about.
