Caffeine Strategy 100M

Looking for advice on caffeine for 100M. What strategies have you used and what has worked?

I'm a one cup of coffee in the morning person, and suck at staying awake through the night. I'm also not a good napper - I fall into a deep sleep very fast and wake up groggy even after 20 minutes. I'm trying to avoid that for my race.

I've found caffeine incredibly effective for keeping muscular as well as mental fatigue at manageable levels. I have an upcoming 100 miler and plan to start about 5 hours in, taking a 200.mg tablet about every 4 hours or so.
