Ask HN: What is your longest coding session?

Some people like George Hotz can code 10 hours straight easily(https://www.youtube.com/watch?v=7Hlb8YX2-W8) and a lot of people are livestreaming 10+ hours coding sessions. I can not code more than 4 hours straight without a break of 20 mins and then continue for another 4 hours.

What is your longest coding session ? What supplements(drinks, pills) did you take during your longest coding session ?
