I've noticed that, for me at least, different coffee types can cause different reactions.

For instance, Burger King coffee makes me nervous; i'm jittery, I literally tremble and I feel highly anxious.

Starbucks doubleshot energy make me hot (temporarily), but gets me through a 12 hour work shift without crashing and thus is my drink of choice. While Starbucks Frappucino (in the bottle) feels "less caffeinated" to me but sometimes can make me feel restless.

I can use up to 1 1/2 scoops of my Foldgers home coffee but 2 scoops will jack me up and make me feel like I need to check in to someones hospital.

I say all this to say, perhaps you can do a bit of testing & adjusting to see what effects you but not to the extent that it harms you.
