I had a nap on the couch while Lucila (cleaning lady) was here cleaning. I woke up for a second when she started vacuuming, but fell right back to sleep. I woke up feeling much better and I almost feel back to "normal." I don't feel any residual depression lurking in the background, so this might be the end of this for a while.
I guess the medication is helping a lot. I was only feeling crappy for a few days.
