Sea Bands.
I have / had a deal of problems with acceptence of turbulence. I got to a stage where I could not or would not fly solo, although I have a ppl and been flying since 1973.It got so bad I was scared to do circuits on all but total calm days. I started having a bit to eat a couple of hours before a flight, and on the advice of an ex RAAF instructor had an apple about an hour before flying. Apparently the acid in the apple has a neuterlising effect on stomach your acid, and so lessens the effect of motion sickness.
I also found by wearing sea bands, designed to stop sea sickness, again a motion problem, helped a great deal. Ginger is good, plus a herbal calmer called valerian, no side affects, just helps lower the worry factor. I find if I have to do a long flight in a comercial aircraft all of the above seems to help.
I have been flying solo lately, but yet to venture out of the 'safty of the circuit area'. It is probably all physco-sematic! (all in the head)
