So I pulled an all nighter last night just because it was difficult for me to fall asleep. I just fell asleep on my couch and took a tiny nap. My bf told me that I had been asleep for about 10-15 minutes. Now I feel at least a little bit rested, but still a little sleepy. I have errands to run and I have to work later on tonight. Is it safe for me to drive? I was just wondering since I don't have much sleep under my belt and even though I might FEEL rested, my body could still feel tired.
