I just cannot stand the nights where I have trouble sleeping because of just the right amount of coffee and long acting ritalin floating around in my body. I try, but do not sleep. Instead, I lay awake and think. I think, and I think; yet, I learn nothing. When one sleeps, his brain goes to work. One part producing a false reality or a dream, while the other sorts through everything you have heard, learned, or discovered over the past few days, maybe even a week, to determine which pieces of information are the most important (deciding this by repetition over several days with good REM sleep in between) and eventually develops a long term protein coded for that memory. Sleep is very necessary for this part of my career as a professional student, but is becoming harder and harder to come by. Perhaps I will get a second prescription for the drug that is not long acting. I want to sleep. I want to sleep. I will not today.
