My wife mentioned possibility of going up into "mountains" for the experience of "cloud forests." Don't knoes to rx for me. (Diamox is probably very cheap, though.)

I only had experience of coca tea once and it did nothing for me. I still got the excruciating headache after going to bed that night. I'm not going to be subjected to any drug screening since left the Army Reserves years ago, but wonder if coca tea would cause a "positive" and for how long after. Anyone know?

Never thought about an airline flight as a "depressurized" challenge and I have never had trouble in a plane or going over passes in CO.

Thanks for the advice. Any suggestions for short stay in Quito?
