I lay out 8 days' of vitamins at a time (because that's how many cannisters will fit in the bowl I keep them in); three doses a day plus very early and before bed. Part of my "leaving the house" routine is setting them out for lunch and dinner, and swallowing the first set on the way out the door.

I also carry a "spare" multi in my purse in case I forget; I will at least get the big important stuff and avoid a crash.

I take a LOT of vitamin C and keep some in my desk drawer at work.
