Anyone that says " I just can't sleep when (fill in the blank)" has never been tired enough.
BTW, the ideal power nap is 20 minutes for most folks- DEEP REM for first 15, then you come back to the surface at 20. Sleep longer,you go deeper again.
For summer weather, I can sleep like a baby in a net hammock. For winter, popcorn at bedtime (carbohydrate loading) and a thin redhead. But I'll do most of my sleeping in the daytime- too busy at night.
What we have here is... failure- to communicate.
