Key point here is that you probably fixed your sleep schedule sometime after high school. Coffee dependency is a pretty common hotfix for a poor sleep schedule. Once you take away the poor sleep schedule, coffee becomes less necessary and more a nice to have.

It'd be interesting seeing the long term effects high school sleep schedules have on people. I wouldn't be surprised if poor sleep patterns in adolescence lead to insomnia and other issues later in life. I definitely felt like my high school sleeping patterns were damaging to my mental and physical health.
