Serious Habits while Coding

So this goes out to all coders out there:
What are your habits while coding or debugging/thinking about your code (if you have any)?

Like my habits are:

• Vaping like I'm just breathing air
  
• Biting my finger nails to the point it hurts
  

A habit while coding is when im almost done I feel the urge to fap and when I do I am lost and try to figure out where I left off

Dunno if this is the same for you guys, But you'd start to randomly get hungry so you'd go eat food, then play music, then play a game and completely forget what you were doing.
