- Do not drink water from a lake or stream unless you filter or purify it. In many places there are nasty parasites such as Giardia lamblia and Cryptosporidium in the unspoiled mountain streams -because they are in the local squirrels and other animals.
- Do not drink sodas, juices, or carbonated beverages during the walk. Gas, belching, and stomach cramping can result. Save these for after the walk.
- Do not drink milk or drinks that contain milk(lattes, cappucchino, chai tea, shakes, etc.) Many people are lactose-intolerant and can experience effects such as nausea, gas, bloating and diarrhea. They may not realize they are lactose-intolerant until they take up exercising, which enhances the effects they may not have noticed sitting at home.

- Do not drink coffee, tea, or other drinks with caffeine. Caffeine is a diuretic and removes water from your body, making you need to urinate more frequently. It can also loosen the stools and cause unpleasantness when out on a walk with few available restrooms. If you need some caffeine to get moving in the morning, limit yourself to the smallest possible amount before walking.
- Do not drink alcoholic beverages. Alcohol also dehydrates the body. After the walk, a nice cold beer may seem perfect, but start with a large glass of water. Do not drink alcohol the evening before a long walk. When walking long distance for several days, avoid alcoholic beverages completely.
As your Guide, I admit that I love coffee, chai tea, and beer, but I follow my own guidelines in general (or I pay the price!).
To enjoy in moderation:
Coffee and Tea
And if alcohol is a problem in your life: Alcoholism
