No, but I have been in situations where I get very little sleep before something important. You should turn everything off and lay down in your bed. Focus on one thing with your eyes closed, say carrot over and over and picture one, or whatever you pick to focus on. Another option is read something, a real paper something for 20 minutes, then turn everything off and get into your sleep position.
The good news is, research shows that a lot of people sleep more than they think. They will report only sleeping 3 hours when they actually slept 6. But, if you have been on the Internet all night your report would most likely be accurate. The people who misreport are trying to sleep lying in bed.
If you usually do sleep during these hours at some point tomorrow you will probably start to crash. The brain actually will “nap” suddenly, momentarily, which makes driving dangerous. If you are in the middle of a conversation it won’t happen, but driving, because of its hypnotic triggers in certain driving conditions, can be dangerous.
