If you were given three of those "Limitless" pills, how would you divide them up and how would you spend your time while on them?

If you haven't seen "Limitless" then I suppose I should explain. These pills are supposed to give you full access to your brain. Meaning, your mental ability would be greatly increased giving you enhanced memory, more attention to detail, faster problem solving skills, increased learning capabilities, etc. You only get three, so how would you use them and why?
