Just a quick update from me in case anyone's interested...
I've now had a couple more lessons and the "avomine the night before" trick has worked very well for me. I do feel a tiny bit drowsy even after a night's sleep (more than usual I mean!), but it is only marginal. I was compos mentis enough to do my first unassisted landing today so as I say it was a marginal effect.
Whilst I've got the instructor in with me I'll continue like this for a couple more lessons, but probably go down to half a tablet the night before and see if that is enough. I'm also still following the other advice of light clothes, plenty of air, (passive) travel bands and ham sandwich/banana an hour or so before.
Best wishes to all the barf battlers out there
