I've been taking an Adderall 20mg pill every monday morning for the past year and a half or so. I helps me kick off my work week in the right direction (I have HORRIBLE cases of the Mondays). I have to take it before lunch otherwise I will be up all night, and I would only get MAYBE 3 hours of sleep before work the next day. So I take it early, and then when I'm ready to pass out that night, I bake myself so I get some sleep. Nine times out of ten, I wake up Tuesday morning feeling absolutely fantastic and ready to go.
There isn't much of a comedown on the 20mg pills since they're lightweight, but the energetic, motivated, focused state that I'm in all day and into the evening is great. I couldn't imagine taking larger dosages.
