Irregular sleep time span.

MAD • I`m 22 years old and I am a customer service representative.


Actually, I wrote this down cause I need help from you guys. I am working for shifting hours and when I sleep it's only for four hours. I wanna sleep more than four hours of course because every time I go to work I am so sleepy. I know as well that it's unhealthy if you only sleep for four hours. What would I do ?
