High Altitude Medicine : How will I know if I am sick?

I'll use The self-report Lake Louise AMS score. http://www.treksafe.com.au/medical/documents/LakeLouisescore_001.pdf 
Based on my symptoms of Headache, N&V, Lightheadedness, and Difficulty Sleeping, I can grade my reactions to altitude changes. Each symptom has a point assignment. The next link is to the Journal of the Royal Society of Medicine, which promotes the Hackett's AMS (Acute Moutain Sickness) as a better system.

Why am I worried about this?  
New evidence suggests that ALL people have swelling of the brain at high altitudes. One hypothesis is that those with high cerebrospinal fluid volume to brain volume experience AMS less often, since they have more skull space with which to accommodate brain swelling.


Just what I need a Swollen Head. Here's what  PETER HACKETT, MD: Associate Professor, University of Washington School of Medicine; Director, Denali Altitude Research Project, Medical Control, Denali National Park Mountaineering Rangers; Emergency Medicine, Grand Junction, Colorado medical advice is to do: take 

400 to 600 mg. of ibuprofen decreased or resolved high-altitude headaches.

In two controlled trials, Ginkgo Biloba (80-120mg. orally twice a day) prevented AMS during ascent to 15,000’ and was 50% effective in an abrupt ascent to 12,500’. Prophylactic aspirin (325mg. every four hours totaling three doses) reduced the incidence of headache from 50 to 7%  .webpages.charter.net/mtwhitneyhiking/ams_nejm_article.doc
