For me it helped - I used them with the seabands, neither were a miracle cure but particularly for my train rides they did help - I was having to catch two trains (get halfway, feeling so sick had to get off, take a break and get on the next one) and after taking the travel calm/morning sickness relief I was able to bare 1 train. Give it a go, it can't hurt and if it does't work you haven't lost anything but if it does work you will wonder why you waited so long.
