I've been awake for 3 days now and I feel fine
Wow, that's a long time! Are you okay from being awake for so long?
I'm doing great and I'll sleep like a baby when this is all done.
After several sleepless nights, the mental effects become more serious. You should see a doctor about trying to catch up on your sleep for your own health.
I don't need a doctor. I think I'm gonna go for a record and try to stay up for 27 days straight.
I applaud your ambitions, but staying awake for that long is humanly impossible and you'd pass out unintentionally. I believe it's best to just sleep when you have to each night, because it can get really unhealthy to not. Don't you worry about your health in the future?
