This isn't normal (relative to a norm, as accepted by a society). There's something wrong with or in me (other than medical condition, of course), but what can I blame for it, this time around? There should be some honest answer for my own question, but I don't know what to say. Of course, I can always say that the medications I take make me drowsy all day, which would be partially true -- yet not the real truth.
For the time being, I'll continue listening to songs of love and pain from The Murder City Devils (http://www.themurdercitydevils.com/).
