Okay so.. I am having horrid diarheeah and I honestly believe it's from taking NyQuil. I didn't react well to it and I have all the weird but common symptoms you can have from it. Um including horrid diarrhea. I took it as directed and it's making me sick! Like I woke up at 9 when I took the medicine at 5am and I was dizzy and sweaty and I showered and ate and drank water the nausea got better but I was ravenous so I ate an entire box of macaroni and then laid down and tried to sleep because I'm loopy. Didn't sleep a bit.
