"I still get nightmares. In fact I get them so often I should be used to them by now. I'm not. No one ever really gets used to nightmares. For a while there I tried every pill imaginable. Anything to curb the fear. Excedrin PMs, Melatonin, L-tryptophan, Valium, Vicodin, quite a few member of the barbatal family. A pretty extensive list, frequently mixed, often matched, with shots of bourbon, a few lung rasping bong hits, sometimes even the vaporous confidence-trip of cocaine. None of it helped. I think it's pretty safe to assume there's no lab sophisticated enough yet to synthesize the kind of chemicals I need. A Nobel Prize to the one who invents that puppy. I'm so tired. Sleep's been stalking me for too long to remember. Inevitable I suppose. Sadly though, I'm not looking forward to the prospect. I say "sadly" because there was a time when I actually enjoyed sleeping. In fact I slept all the time."
