Don't you think that part of this could be stress? Also potentially dehydration. I have had eye twitches a couple times during long road trips where I drank Red Bull or Monster to keep focused, and was not drinking enough water. But I have never had twitching from caffeine under normal circumstances, since I usually drink 2 parts water for every part caffeinated drink (lots of bathroom breaks).

Probably not, I drink a lot of water, especially during hot weather -- I walk to work and back twice a day no matter the weather.
