If you say you only erred once or twice then it looks as though you adjusted fairly quickly - and probably a couple more flights would have ironed those out. In other words one adjusts quicker than you would think.
One point to note though. You normally have your left hand on a yoke because most aircraft have the throttle(s) in the middle. All the aircraft I have flown with sticks have the throttle on the port cockpit side. Maybe the fact that you are gripping a stick already tunes the brain into accepting the behavioural pattern is different.
I'd have to fly an aircraft with a yoke and left hand throttles to see if I would really get confused! Don't know if such a beast exists - that us mere mortals could get to fly that is.. Right hand seat in a Staggerwing qualifies but I only had 20 minutes in that..
