Do you feel exhausted after a pair programming session?

I haven't done pair programming (PP) in a while, but our team has practiced it for 1 or 2 sprints in the past. And my experience is kind of mixed.

PP is good and all, but after each session, I feel exhausted because I have to talk and think and code at the same time. Usually lost my voice and feel dizzy.

I wonder how others think about it here in HN? Any tips?
