I have had insomnia for most of my adult life, but RK, I suspect this is just a blip for you and you will get back to regular sleeping patterns soon.
That said, I would like to strangle every single person who says no one ever died from lack of sleep. LOL. It does cause problems.
There was an excellent show on TV last week on Dateline and research shows that people may very well die with lack of sleep. It's proven that people begin to lose their sanity after 4 or 5 days without sleep. Research also shows that chronic insomnia is as bad for you, as not eating well or never exercising. Your body never has a chance to regroup. Dateline showed a link between chronic insomnia and diabetes and that insomnia should now become a marker for diabetes along with being overweight, etc.
Dateline also talked about the link between car accidents and other accidents and lack of sleep. It's not an issue to be minimalized.
