Thank you for your reply, it is very informative and I shall not take the
Travella tablets! Are you aware of any over-the-counter traditional
medications which do not cause drowsiness and would be safe to use
with my condition? I am usually a good sailor so hope that I shall be
fine, but it is going to be windy in the English Channel tonight!
Thank you - I have some ginger sweets so shall take those with me!
