Little word of advice before we begin:

Guys, please remember that at the end of the day this is just an internet challenge. Please do not do anything stupid during this month that will impact the rest of your life.

If you're struggling so much that you can't study or even work, don't fail or get fired for this challenge. The real reward is only bragging rights anyway. Some of you may be trying to fight addiction and that's good, but don't throw everything else away for this. There's always other times to try to quit.
