When are you most alert?
GrandMasterBirt: "# Afternoon tiredness can be overcome by coffee or a 20 minute nap (ideally both, since caffeine takes 20 minutes before it gets through your system).
# If you like to limit your caffeine intake, you may want to save your quota for when you experience your natural dip. "Evil! I don't drink caffeine! I usually get 6-7 hrs of sleep but I am most awake at around 10pm-12 or 1 am.I found NOT drinking caffeine improves my overall alertness. Without it I set my own rhythm for waking up, sleeping, being tired, etc. With it I just get these spikes of alert after drinking coffee, then even more down, then more alert, etc. It makes my day completely unbearable, and god forbid I don't get my coffee.However I noticed my most alert time is mainly due to the fact that around 10pm to 1am nobody bothers me. I can pretty much do whatever I want without anyone pestering me for "honey-dos" or any distractions.
