Your sister’s symptoms are classic for Motion Sickness (Kinetosis).
It occurs because the inner ear (balance system) and the eyes send mismatched signals to the brain during travel, leading to:
• Nausea
• Vomiting
• Belching
• Dizziness
• Cold sweat
• Breathlessness (from anxiety and overbreathing during nausea)
This is a benign and very treatable condition.
Best Medicines for Motion Sickness (scientifically proven)
1. Dimenhydrinate 50 mg (Dramamine)
• Take 1 tablet 30–60 minutes before travel
• Prevents vomiting and nausea
• Dose can be repeated every 6–8 hours if long journey
• Safe and widely used
2. Cinnarizine 25 mg
• Very effective for dizziness + nausea
• Take 1 tablet 1 hour before journey
