Do you normally sleep 10 hours long, or is it just a result of the situation that allows you to wake up in the afternoon?
I do (on non-school days), and it completely messes up my sleep cycle, since I typically stay awake longer than 14 hours a day, which results in >24-hour sleep-wake cycles.
Here are my bad habits (all of these are nervous habits):
- Chewing things. Especially plastic. ESPECIALLY bottlecaps, to the point people around me just confiscate them from me when I buy bottles so I can't chew them. Like I'm super orally fixated and for awhile I was buying chewing gum for this purpose but they discontinued my favourite flavour so I just reverted to chewing plastic...
- Clenching/grinding my teeth from stress. It's so bad I have to get a (rather expensive) dental splint (when I can afford so much... zzz) to train me out of the habit, because I get jaw/facial pain from it constantly. T_T
- Tying knots in things, especially my hair.
- Undoing my hair randomly and consequently losing all my hair ties.
- Talking into a pillow instead of directly into the microphone when I'm on Skype or the phone.
On the bright side, I used to have a really bad habit of falling asleep with my glasses on (this still happens 'cause sometimes I fall asleep at the table/computer/wherever, but not when I go to bed anymore! Now I don't break or lose my glasses :D It took awhile of training, but I put them away before I go to sleep now.
