Morning Jolt Of Caffeine Might Mask Serious Sleep Problems:
With the holiday season's hustle and bustle in full swing, most of us will race to our favorite coffee shop to get that caffeine boost to make it through the day. However, that daily jolt that we crave might be the reason we need the caffeine in the first place.
Insufficient Sleep Raises Risk Of Diabetes, Study Suggests:

Regarding the sleep survey: Rather than concluding that all-nighters lead to lower grades, is it not possible that poor study habits, like leaving things to the night before, lead to lower grades?

I love any news about sleeping behaviour... this is a very interesting subject
