Thanks for your post everyone.
I gave the ginger a try. Went for a check flight in a hot aircraft. Did a couple of steep turns and stalls and I held up ok. A few belches and slight unease, but safe and comfortable.
I tried kwells tablets, they work but if I take more than half a tablet my head goes into stalker weirdo mode because too much of that stuff send my head spinning.
I hope the ginger works in the long run.
