Most of the people are facing Early waking up problem, specially  technical field  People .The solution for waking up problem is a website called Kuku Klok, combined with turning  speakers all the way up.

Once you load the page, you simply set the time you'd like to wake up. Select the sound you want (previewing it helps to test if your speaker volume is up enough). And then click SET ALARM.

The great thing about this website is that it will work even if your internet connection goes down after setting the alarm. (In fact you can use this site offline by doing File Save As HTML Complete).

Use the Kuku Klok at kukuklok.com
