i lost some thing

Its not exactly sleep. But the sleepy feeling when you are bored. I almost lost it. I remember in college, i used to feel sleepy. The two years of predegree, had some heavy tests for us, like the 5 hour daily chemistry tuitions. I was a little interested in chemistry those days, otherwise, i would have joined my friends in dozing off in the class room. The greatest test for me was the physics classes in engineering collge days, by which time i have lost interest in science. It was hard battle, where i failed a lot of times. I also had this sleepiness when i was working in trivandrum. But come hyderabad, and i have lost it. My colleague is sleeping in his chair sitting in the next cubicle, most of the guys are yawning and i feel fully up. Last day, our CTO was giving a lecture on future plans and i see every body, yawning away, i was rock steady, all ears. It a feel good loss, though, i also lost 3 kgs and quarter of my sleeping capacity as part of the package.
