Most of the time I do the whole get 4-5 hours of sleep. In fact, last night I went to bed at 3:30am and woke up at 6:00. I did have an hour nap during the day though. I normally like to go to bed earlier (12) and wake up earlier (4:30-5). I find my self a lot more productive early in the morning rather than late at night.

For me, it's not about "get 25% more done". It's more about being able to still spend time with family when I need too and get work done while everyone else is still asleep. It's very much a work life balance tool for me. I can't go weeks on 4 hours though. If I do 4 hours consistently in about 10 days I crash and need a full 8 hours for a day or two.
