I used to have a group of friends come over once a week and we would play party games until late in the night on Wii U or sports games on XBox 360. Normally, I would have them over the night before my day off. But, one time I stayed up all night playing Raw vs. Smackdown 2007 on XBox with them and then went to work for my 7am-3:30 pm job in the morning. There was a Dunkin Donuts in the building that didn't open until 8am, so that first hour, I kept nodding off on my feet. I would snap to everytime someone passed me and said good morning. At 8am, the lighting came on to normal (they would set it to dim overnight), and the Dunkin Donuts opened and I got coffee, so I was fine after that.
Also, I used to get super tired on long drives during the early morning or late night hours. Then, I tried 5 Hour Energy and I never had that problem again.
