I was very skeptical before purchasing this but decided to give it a go. My 9 year old zuchon has always been terrible in car rides, usually getting motion sickness and throwing up within 30-40 mins. We were getting ready for a 12hr road trip from Melbourne to Sydney and I bought this the day before. I gave his doses (dropped it on a small treat) at 4am, 4:15, 4:30 and 4:45am before we set off just after 5am. We did stop 3 times throughout the road trip and I topped up the doses on each break. I noticed that even though he was awake the whole time, he didn't drool or show the normal symptoms he usually does before he throws up, so I was very comforted. On the journey back, i only gave him 1 dose in the morning and that was it. On this return journey, I saw that he was even relaxed enough to nap. I'm soooooo grateful for this product and highly recommend giving it a go!
