I used to be a hardcore caffeine aficionado. I learned that if I took it after lunch, my sleep would be impacted, not noticeably on one day but the effect stacks since it's a daily habit and that long term rejuvenation is worse. Eventually my father listened to some podcast and became opinionated about artificial caffeine and didn't want me to drink energy drinks.
