Has anyone used this and does it work? Alfie is suffering with travel sickness and he really didn't want to get in the car today. He is ok up to about 5 miles and then he is sick. It's upsetting to see him being ill in this way. I really want to try a natural remedy for this, so if anyone has any other useful ideas, please let me know. Also, will he always suffer or can he grow out of it? He is 11 weeks now.
