This is actually a good line of thinking. Although you feel your best and think the clearest when you've kept near-perfect sleep and nutrition hygene, sometimes you need a different bag of emotions to get an idea. That could mean fasting, sleep deprivation, alcohol, caffeine, smoking... However, not knowing which one is useful to you at any time, it's hard to know which is the most effective for work. But being mostly sober/mostly healthy is known to be the best (long-term) for staying alive and well, and startups are, on a human scale, a long-term game. You don't make $1,000,000 because you stayed up all night to ship.
