Kruger2Canyon Properties has an easy solution to Car Sickness.
All one has to do is get the kids to suck a hard sweet that is based on any citrus flavour. Lemon and Lime works really well. Orange is just as good.
Suitable sweets are Beacon Sparkles and also Super C’s.
Avoid chocolate and ice cream.
Fresh air in the car also helps. Even if you have the air conditioner on, leave a window slightly open.
