Those Sealegs pills work great. I get chronic motion sickness and those work great on me.Good Luck :)
I also suffer from motion sickness (something to do with being called Philippa?) I find the sealegs made me very drowse. In England we can get a homoeopathic remedy also wrist bands I find the two work very well together with no side effects. It also works well if I have to travel in the back of the car.
