Good for you! Always a fine thing to get some "You" time alone in the pineys.
Hey...have you thought about an Ursack http://ursack.com
for food. No throwing. just tie it off on a tree and good-night Boo-Boo.
As to the chill....sometimes that just seems to happen around that time of morn'. All the calories have been burned off and it is the chilliest time fro around 4 to 6.
when I get up to pee in the wee hours I tend to slip on an extra shirt or even pants so as to ward of the creeping-chill. Sometimes it happens...sometimes not. Are you wearing a hat? That surely helps.
