When flying, it's advisable to avoid certain drinks that can contribute to dehydration, discomfort, or exacerbate jet lag. Here are some drinks to be cautious about:

1. Alcohol: While it's common for passengers to enjoy a drink during a flight, alcohol can contribute to dehydration, especially at higher altitudes where the air is drier. It's essential to consume alcohol in moderation and balance it with water intake.

2. Caffeinated Beverages: Drinks like coffee, tea, and caffeinated sodas can have a diuretic effect, leading to increased urine production and potential dehydration. If you choose to consume caffeinated beverages, it's essential to balance them with water to stay hydrated.

6. Large Amounts of Dairy: Consuming large quantities of dairy, such as whole milk
