A Psychological Question

I am an introvert and-- for me-- being around people is like drinking alcohol: an initial sugar rush, loss of inhibitions, and the usual giddiness-- but after too much time with people, the inevitable hang-over results and I need time alone to re-charge . . . and I wonder if being an extrovert is the opposite: if time alone, time without other people to interact with, actually drains an extrovert-- the way Bill Compton drains Sookie Stackhouse in the back of Alceide's truck-- and they need to be around people to feel normal, energetic, and grounded again.
