Car Sickness

[thesockmonsterofdoom]

we have been putting of visiting il's nearly all year as both dd's are really car sick, they live about 3.5hour drive away and dd's can be sick on a 20min journey to the local mall. we have tried travelease but they dont really do anything. I am now dreding the journey, is there anything better, has anyone tried the other tablets available, i think they are joyriders (sounds like a condom) and sealegs. I dont want to try something and it not work when we are on a long journey iyswim.
Dds are 5 and 2. The 2yo is the worst.

We've used sealegs for DS2 in the past, they were quite sucessful. Also used those acupressure wrist bands which were as sucessful as the pills, in our experience

I use the wrist bands myself, but wasnt sure they would work and not get pulled off the lo's.
I know mum used to give me sealegs, do they taste nasty or anything?
