....and your right in what your saying about alcohol. It has 1 plus effect though..it makes the blood thinner and thus you can tranport more O2 to the smaller vessels on high altutude. During my last expedition on everest we had some tjeck people with us and they were drinking a lot saying it was good for acclimatisation..and they had astonisly good O2 value's in their blood. Also the russiens (north direct on Everest) were drunck alot and they made the summit heheheh.
We let our expedition medical team do research about the subject and they came up with a lot of different answers. Concluded that they dont realy know actuallly. So we decided to stay sober
