For the jittery-ness maybe the coffee bean and not just the caffeine doesn't agree with you.
I normally drink my coffee black, but my dad finds that drinking coffee with milk upsets his stomach. He is not lactose intolerant and can forexample eat a bowl of cereal with no problem. Something about the combo of coffee and milk or cream upsets his stomach though.
Even though I hate decaf, I'd say try that without the milk if you are craving the taste of a cup of coffee. You can try a non-dairy creamer.
Coffee has WAY more in it than caffeine. Where an energy drink usually has synthetic caffeine added, coffee has an insane array of terpenes, acids, alcohols, xanthines, and so forth. Your body most likely has a sensitivity to one or more of these other natural chemicals.
