Day 117:

Ive noticed when you're getting between 6.5-7 hours of sleep you note you feel good, if its less you note tired. Maybe try to aim for 7 and if you get 6.5 you'll still feel good?

Thanks a ton for this. I will aim for more. You're the 2nd person who has pointed out something so obvious that I didn't even see myself.

How do you keep track of all this. Looks like excel, but like one big sheet?

Yep, all in a book.
