To avoid sleep,

Follow some exercises to ease your neck & shoulder pain,

Move to the right and then to the left,

After that, move to the left and then to the right,

Just follow. Don't force yourself to do 360 degrees, 180 degreeswill do. Bend down a bit like you gonna faint. Repeat a few times till you're bored,

Grab anything on your desk and smash your head hard. If you are still sleepy smash harder,

After that move your feet and swing your body a bit. Do it like it's nobody's business and remember to smile,

Move your feet and body just a bit.... Do it like there's no problem at all....

And now more aggressive! Don't bother about what others say,

Let go of all your stress....

If your boss ask what you are doing, move your head slowly like this and tell them you're dying in the office,

When your boss walks off, get your colleague to join you and move your body like this. The more the merrier...

Finally, dance like a cat.....

If you are still sleepy despite all these,

Just grab your small pillow and sleep under your desk (AT YOUR OWN RISK)
