Turns out our addictions to our smartphones and laptops aren't just affecting our love lives and vacation time.

According to AOL's E-Mail Addiction study for 2007, 40 percent of e-mail users have checked their e-mail in the middle of the night. Which means, people are sleeping with their laptops, smartphones (ie BlackBerries, iPhones and Treos) right at their bed side.

Apparently men are more likely to check their e-mail in the middle of the night, with 44 percent saying they've checked vs. 36 percent of women.

I can't say I've ever woken up to check e-mail on my computer, but whenever I see the red light blinking on my BlackBerry I do reach over and sleepily check my messages. Are you guilty of checking your mail in the night?
