insomnia
"I've been on Ambien for 10 years.. Although my tolerance has gone up it still does the job....I was looking fwd to Belsomra, I took 15 mg at 1025pm and felt nothing,,
I took additional 5 mg and it made me sleep for two hours I woke up at 12:30 aM with a headache and a hangover.  The rest of the night was uncomfortable torture.. I felt  really tired but could not fall asleep.. Is this talk about Belsomr needing one or two weeks to be affected valid?  Pretty disappointing fancy package with a fancy price and a miserable me sleep . Have others experience complete misery on the first night?"
