I am amazed at the amount of physical difficulties incurred during this Everest Base Camp trek...with no or little sleep, a stomach bug, and high blood pressure/pulse, I knew the risks were too much..infact, cost me two days in the hospital.  Others incurred a lung infection, resulting in two days in the hospital after being helicoptered out, a broken/sprained ankle resulting in a flight out and casting....a flight out due to breathing difficulties. .....others who made it, some have respiratory difficulties after coming back down......and there are others who have no residual effects.

If I were to do it again..don't think I will...I would come much earlier,  to rest prior to the trek and adjust for being half way around the world...to sleep a lot...take meds ahead of time for possible digestive system bugs.....consider taking Diamox, which enables the blood to carry more oxygen..

Or I could just stay on level ground.,...
