I usually can drink one cup, whereas I used to drink 3-4 cups. It affected my balance more than my tremors. I will say once more that my chiropractor has stopped my head tremors.

My husband said coffee makes it worse. Instant not too much, café coffee has a big effect.

i would beleive it would if cafeen coffee you are drinking it could lead to greater tremors

I don't usually drink coffee. It would seem like the caffeine would affect the tremors.

I find that coffee makes my tremors worse so have restricted it to one cup a day in the morning.
