I've heard that men are afraid of comittment... not this one! When I commit to a nap, it's for a couple of hours at least. Trouble is, I awake (if you want to call it that) so groggy that it takes another hour just to get functional again. I feel like I'm drugged when I'm in that state.
Not a commitment problem. I sleep 20-30 minutes because that's all I can sleep, and, once again, I am instantly awake, ready to start a new "day."
