Hey Casej44,
I went in August last year and the tips throughout this thread continue to apply.
There isn't anything specifically I can recommend for FSP except maybe getting in the air for a few hours prior to heading down, even if you're not the one in control (maybe especially if you're not). I had mild air sickness at the start but I knew it was probably coming so I was ready and knew my symptoms haha.
Also chair flying, as ridiculous as it may look, was immensely helpful.
Fly safe and merry Christmas!
