I also know that I ought to cut out caffeine. Dude, I'm exhausted all the time. Need a cup of coffee just to kick-start me. Keep drinking it so I won't fall down. Lose the coffee,lose that semblance of functionality.
What I really hate is when when part of my bodyfuckery precludes doing that which ought to help another area of the bodyfuckery.
