Then, when you arrive in Nepal, it will not seem like such a task!
You will need to be drinking 4-5 liters of water per day when you are on the trek.  This is essential to how you will feel and your success on the trek.  It is a good idea to get used to drinking 3-4 liters of water per day before you arrive in Nepal.  We suggest that you get your body used to drinking this much water each day before you start the trip.  Then, when you arrive in Nepal, it will not seem like such a task!  Also, you dehydrate very quickly on a plane, so make sure that when you are traveling to Nepal that you are drinking plenty of water!  Don’t arrive in Nepal already dehydrated.
