Altitude Sickness
One of the things you will get warned about in Tibet is altitude sickness.It will usually strike about 6 hours after landing in Lhasa and can consist of headaches, dizziness, nausea , loss of apetite and lack of sleep.The ways to get round this are to drink water like its going out of fashion (around 3 litres a day) for the first few days you will pee like hell but stick with it and you'll get back to normal.Also, don't over do it in the first few days, have a lot of rest and don't visit too many monasteries or the Potala Palace where there are loads of steps to climb.If you can get hold of it, take half a Diamox tablet twice a day. Its hard to get in the UK as doctors can't prescribe it for altitude sickness, although you can get it on private prescription from a travel clinic.If you are travelling to Lhasa via Kathmandu pop into a Pharmacy and buy it over the counter, its very cheap....
