I can't take Ambien/Lunesta...does not do squat. ABSOLUTELY NOTHING!!!
However I use Seroquel for sleep and literally this is what it does to me:
My Brain: ...**going... going... going..gotta.... pay the cable bill.....thinking about the Universe***do di do di dooo***...hmmm i want some popcorn.....***do di do di dooo***...
(BRAIN SHUTS OFF).................wake up the next morning!
The first time I took it...I woke up to use the restroom and could not make it back to the bed...woke up in the hallway on the floor outside the bedroom door. Serious stuff...
