I only use Caffeine now when I'm really low on sleep and stop all intake after that. In high school, I would drink tons of caffeine every day.

I didn't realize until later in life that it contributes to my anxiety. I sleep much better without it and can actually get more work done. My anxiety is also reduced to almost nothing.

I think I got into a habit of just drinking coffee every day, that I didn't really think about it.
