Madonna's longtime pal Debi Mazar has become a crusader for the sleep deprived after suffering insomnia for years. The Entourage actress is using her celebrity to urge others who suffer from sleeplessness to check out a new website, BedsideBriefings.com, which offers help to those who can't get to sleep.

She tells Life & Style magazine, "My insomnia started in my mid-20s. It got to the point where my immune system would give out. It affected my concentration level and being able to perform on the job."

Now 44, Mazar reveals she eventually got the help she needed from her doctor, but now there's online help for insomnia sufferers. She adds, "The website lists factors that affect sleep, consequences of lack of sleep and then tips on how to help you sleep." (KL/LS/IG)
