I used heroin with a girl one time in 2006 or so. I developed an elaborate fantasy around this thereafter which involved nap times . I've given up on keeping up with the weird fantasy, though I still remember the girl from time to time. But I still value my sleep and even purchase myself a special pillow (firm) even though I regret ever using heroin and never intend to do so again.
The proper way to nap is to slug down a cup of coffee, and set your alarm for 40 minutes. I reject the way the rest of you nap!
