Tips to reduce altitude sickness:

Symptoms usually begin within a few hours of arriving at a new elevation. Some people compare the symptoms to those of a hangover. Headaches, fatigue, and nausea are all common when experiencing altitude sickness. 

Your body usually adjusts to a new altitude within 24-36 hours, so avoid any strenuous activity on your first day or two. Even very active people are susceptible to altitude sickness, especially during physical activity.

• Drinking more water than usual is also very important and will help reduce or prevent symptoms. Stock up ! You need at least 4 liters of water every day on a high altitude trek. Other things to avoid include salty foods, caffeine, and alcohol. 

• Drinking alcohol at high altitudes often causes a magnified effect.

• A medication called Diamox is used by some people. What does it do ?

  Diamox is a diuretic. Side effects for short term use are basically non existent.

  In summary, this medicine helps you acclimate faster by increasing your breathing rate.

  So for most treks that gain altitude too quickly, people taking the preventive medication - Diamox, really helps. Especially if your trek climbs above 13,000-14,000 ft.

• Diet is a equally important role. It’s important to eat well at high altitude, but not eat too much.

• It is suggested NOT to have a diet that’s very high on protein. High protein is harder for your body to break down. A low-salt, wholesome meal may be more beneficial.

• It is believed that carbohydrate diets can improve energy balance. Eat a high carbohydrate diet before and during the acclimation periods. This can include pastas, breads, fruits, and potato based meals.
