I was reading that Ibuprofen works about as well in a recent study in California. I don't know where I saw it but it may have been here. Water , water , water ! Come down if you experience it as it can kill you . It's brain swelling that causes the headache and that is serious business.
I used it last year on a goat hunt. Did not get sick like I did the year before in the same area without the stuff. Have more on order now for this year.
You guys should check out some stuff made in Gunnison, Colorado called acclimate. It works really well and is cheaper than the wilderness athlete stuff
I used the WA altitude advantage last year before heading to CO. I thought that there was a noticeable difference, although it may have been more mental than anything. I would take it again! It gives you some wierd tasting burps as well.
