I actually like turbulance... I find it restful... however.. one way of getting over it - -or accepting it - is to find something to focus on.. either keep something in your hand, or find a spot on the plane to look at...
The only time I've ever found the turbulance a little unnerving was when we were about 30,000 feet and the pilot couldn't find a good altitute where we weren't bouncing and people were using air sick bags. (want me to get nauseaus - have someone next to me start tossing their cookies) At some point the pilot comes on and says not to worry because the airplanes are designed to take this kind of abuse... (I wasn't the least bit worried until the guy in charge told me not to worry) eventually we settled down.
Get yourself an aisle seat, in the middle of the plane... you will feel the turbulance the least there.. and bring something to keep you occupied.... And don't sit anywhere near people who fly a lot for a living because we might find it necesaray to start sharing war stories of the emergency landings we've made and the crashes we've walked away from...
Flying is safer than driving, the guy flying the plane knows what he's doing and the plane really can take the torture. Think of all the fun you'll have at your destination.
