I haven't gotten sick (cold, flu, strep, etc) since 6th grade and I'm now in 10th. But the thing is, if I don't sleep for at least 7 hours the night before, I get a lot of problems the next day. Some examples are not walking straight, slurring my speech, my eyes keep rolling around, and i start imagining all kinds or crap. LOL it sounds like I'm high, but I promise I'm not. Can someone please explain this?
