Don't drive unless you've had a solid 8 hours of restful sleep. Drowsy driving is actually more lethal.

Does is it still sound easy?

No. Most people would go easy on someone who stays up late studying or has some insomnia, and still drives the next day. Or a designated driver that got to bed late because they drove their friends home. But why? They are impaired and a threat to life as much or more than someone who has a glass of wine or two with dinner and then drives.
