I am actually a pretty good sleeper. I naturally sleep about 8 hours a day, and if I wake up naturally, I usually wake up feeling pretty good (haha...people are going to hate me for that).

The problem is when I go to bed really late and/or need to wake up earlier than I would naturally. As it turns out, I am more affected by when I wake up in my sleep cycle than I am by how long I sleep. If I need to wake up at 7:30am for a call with east coast people, the wakemate would wake me up at "around" 7:30 (you can set a hard stop), during the point in my sleep cycle in which I am most amenable to being woken up. It's the difference between feeling like shit, and feeling like I woke up naturally.
