Pulling off all-nighters can usually mean three things:

1. You are unproductive.
2. You screwed something up.
3. You have a health issue.

I guess you are in the 2nd group, perhaps mixed in with a little bit of the 1st. Personally, I am in the 4rd group and it's not fun. Despite having a good night sleep right now, I am sightly jaded and around 70% alert, but it's ok if nothing happens the rest of the day. My medication for today so far was:

• 60mg of Ritalin
• 400mg caffeine pills
• 2 liters of espresso
• 1 liter of cola light
• plenty of nicotine

Bottom line: If you need some advise from a professional, just ask. :-)
