So, I usually sleep 6-7 hours a night, but came down with something. I've been feeling queasy and coughing a lot. Last night, despite it being NYE, I laid down at 730 pm and didn't wake up until 730 am. Actually I woke up 5 or 6 times during the night, but got back to sleep within 15 mins each time. This is unusual as well. I've never slept over 10 hours before, even when sick, even the night after a marathon. I just assumed I have a little cold that would go away in a few days. Is this a sign of anything worse?
