Just short of Garel I began to experience the effects of high altitude and suddenly developed headache and nausea. I could hardly make it to our resting place and for once I started to imagine that its all over for me as far as going any further is concerned. The feeling was really sickening and terrible.I just managed to just lay down early and was fighting through out the night against the sickness. But by the grace of Allah I was absolutely fine in the morning and my enthusiasm returning back quickly. So if this happens to anyone of you, just dont panic, take some good rest and the effect should go off well in time.
