Lucky you. Some people are more effected by caffeine than others. My eldest daughter reports similar ups and downs as I do, my other daughter reports no large effects.

Must be genetic, then.

"Some people get jumpy after drinking a single cup of coffee, while others can gulp down a Venti Americano without feeling a thing. Part of that variability is due to the development of tolerance by regular coffee drinkers; but there are genetic differences in how people metabolize caffeine as well. "
