dej,

been there, done that.
my dr sent me to a sleep dr. they wanted a sleep and documented that i had pain (from my brain waves). that was 1 thing. they also found sleep apnea.
i had a very good dr. we tried a lot of meds too. i also tried lunesta but the only thing that worked was ambien CR. that plus some trazodone.

i don't abuse meds either. i don't sleep all thru the nite but i do get a few hrs in a row. i wake up, pee, and can fall back alseep. they said my sleep study showed i didn't fall into REM sleep at all.

lack of sleep can really affect your health. maybe you should see a specialist.
and, i had to say this, but all the activities you're doing when you can't sleep are all wrong. they're too stimulating to the brain. that's what i was told.
no computer, no tv. i think he told me i could read but turning on the light will screw up your body's melatonin levels. i actually shut off my lites about an hr before bedtime to try and get my levels up.

please let us know how you're doing with this.
