[Question] How do I use caffeine optimally?

I just started a new job, and I’m really excited for the potential of drinking coffee, but I’m worried about dependency or other negative effects.

I don’t want to be upset or feel unwell if I don’t have coffee, and I don’t want any long-term negative health effects from drinking coffee.

Is there any research on caffeine schedules or does anyone have any personal experience with using caffeine?
