There are several anti sickness applications besides the usual car/seasickness tablets, which tend to make you drowsy, on the market and the two most popular are the patch for behind the ear and the wrist band which works on acupuncture points and these should be available to your local pharmacy. It is also possible that a change of cruise ship might be advantageous as MV Discovery is an older ship and is quite small, she is well known for moving about a bit although I realise that the advantage is that she does reach the ports that others fail to reach. When it gets extra rough try an injection on board at the Medical centre, I have friends who swear by that, although it does cost money. I do sympathise with you and wish you well but do keep experimenting with cures, one day we might find something totally reliable....Yours Nei
