I do. For example, given that I'm running on about 3 hours of sleep over the last two days, my body aches and I have some deep pain in certain joints and muscles. Not to mention nearly every single joint that pops when I move. Damn I'm tired.
I know the feeling.my whole body enjoys aching, apparently.
Could I simply be sleep deprived? I wonder. I have no qualms with sleeping more to fix my neck, shoulders, and back. I really, really like sleep, but just don't get a lot because of school. To get what I think is enough, I'd have to be asleep every night at about 9:30pm since I have to be awake at about 5:30am.
9:30 isn't happening.
