how to avoid yawn?

In my case I am yawning for the whole day and feeling always tired eventhough I have a good sleep for 8 Hours. I am unable to come out of this even after I try through drinking water, washing my face, doing some breathing exercise, eating, chewing etc., My works get spoiled every day because of this. When I contacted the doctor he suggest for an operation which I feel too extreme. I seek advise from any of our readers to get rid from this problem

yawning is mainly due to the lack of oxygen content in the human body the best method therefore is to consume oxygen but people do not consume oxygen directly :) hence , water that is considered as the richest source of oxygen has to be consumed some people say that i was tired so i am yawning no that is not the case in your case i guess you would not feel tired just after you wake uo early in the morning :) so the best solution for you would be to drink say about a water of fresh water so that there is enough oxygen in your body :) then just to remove your sleep , wash your face with fresh cold water :) this washes out your sleepy eyes and you can then concentrate to the max :)
