Same. I'm right-handed, but switch to left-handed mousing when my wrist started hurting. Now I switch back and forth several times per week. Nipped my nascent carpal tunnel in the bud I think.
What's interesting is that it's not as hard as it sounds. You basically just reverse your left/right click settings and your brain picks it up very quickly.
Hmmm. I never switch the buttons and TBH I never understood why that option was there. It's no harder to move between 2 (or 3) buttons with my index finger on either hand.
Do some people use different fingers on the different buttons?
