I have to be at work in a little over 3 hours

stay awake, personal experience

Sleep is for the weak ;) Nah at least rest your body without sleeping, else you'll be tired for the day.

I always find the day is easier to get through with even a few hours sleep then none, but then again I dont do well with no sleep.

Set several alarms and one across the room. Having a dog really helps getting up at morning. So either set a lot of alarms and go to sleep or quickly get a dog that needs to pee/poo in 6 hours. If you don't rest at all though, you will feel like shit probably.

I had this experience before. I would say having some sleep is better than none. My experience was I had work at 8:00 AM, but started sleeping at 4:30+ish AM. The thing is I have to wake up at least 6:30 AM to eat, shower, and drive to work. So had 2-ish hours of sleep. Personally I found those 2 hours helpful to at least function and stay alert. So sleep right away right now. But as smallDaddy said, have more than one alarm. Like he said, one right next to you and one away from you so you have to get up and turn that one off. Hope your day works out!
