They should work but they will probably make you sleepy....so I hope someone else is going to be doing the driving
As for the sickness bands, if they don't work, then they aren't in the right position(or aren't snug/tight enough). You need to move them up a little bit or down a little bit.
One of the anaesthetists that I worked with, was absolutely brilliant at detemining where pressure should be applied to stop nausea and vomiting. We had a lady who had persistent pregnancy sickness and he came along and showeed her where to apply pressure........her nausea and vomiting stopped just like that (click of the fingers).........from then on, she was able to control the probelm herself and go home.
It was amazing.
Hope you get sorted Shaz.
