I also cut down on soda and caffein 100%, and I feel much better overall. I could never go back. I used to get so addicted. When I began my internship I would be going through up to 10 shitty drinks a day. As soon as I completely cut them out my productivity, focus and energy dramatically increased.

Everyone is telling me to wake up early...eurgh. I'm going to do it but I'm really going to miss sleeping in, especially during the weekend where I go to bed at 3-6am on average.
