I shake like a leaf and have jerky muscle movements thanks to the Risperidone I've been on for 4 years. (Anticholinergics don't seem to be helping). But I don't find the few cappuccinos I have during the day make it worse. It would take a huge amount of coffee (say 10 cups) to give me the hyped up feeling. If anything I find 3 or so cappuccinos rather soothing.
