Thanks for the replies. I don't want to medicate myself.
Whopity & Pace your right about needing to build a resistance to it.
Having thought about it; over the last few years I've just flown recreationally. I've been fussy about the days I chose to go flying & opted to go up only in smooth air or light turbulence mainly because most flight's I take pax & also flying is far more enjoyable & you get more bang for your buck if you fly in smooth air so yesterday I was a fish out of water in the rough conditions.
