No I didn't ask the doctor. Go thru regular checkup once a month and nothing came up so I don't bother.

As far as I remember it wasn't always like that. Eventually at some point around my 20s I start working more and more hours and never got "break". Eventually I think my body got used to _knowing_ how many hours per night it can expect and adjusted. That or perhaps a heart attack is coming any day now at 35 (knock on the wood)
