Everything in moderation is mostly OK.

It takes a lot of coffee to create jitters in me. Coffee does mitigate the waves of fatigue. Energy drinks make me me feel terrible for days, jitters then waves of fatigue.

Coffee limited to one cup and/or watered down causes me no problems with my tremor, including my essential tremor.

I have always enjoyed a nice strong latte. I tried to limit my coffee intake to manage tremors. I found that the benefits of caffeine outweigh the tremor jitteriness. I also have to limit when I enjoy my coffee. I have difficulty sleeping so I try to limit my caffeine intake to one cup before 12 o’clock.

I haven’t had any issues with caffeine. I drink a good sized mocha almost everyday.
