Texting and Sleep Deprivation

So, are you yawning today and pounding the caffeine just to stay awake? Sassy Scrubs wants to know if sleep deprivation associated with excess texting is affecting you. I just read an article regarding the texting practices of teens and college students - specifically regarding their inability to "turn off" and go to sleep. It seems that texting a friend, or a group of friends, is so appealing to this group that they sacrifice their sleep so they can stay in the loop, and be connected. Sort of like the old water cooler - or nurses' desk - for sharing gossip and information. The fact that many use their cell phones as alarm clocks seems to compound the problem - the devices are turned on, and receiving messages, so the messages must be answered. Immediately.

Is this the only age group subject to these pressures? Have you ever pulled an all-nighter just texting your friends, even though you knew you'd pay for it the next day with exhaustion? Has this affected your ability to do your job to the best of your ability? Is this a problem in your own home and what practices have you put into place to manage cell phone use with your family members?
