insomnia
"I started taking Ambien CR 12.5mg for insomnia and it initially worked very well. Sometime around my 4th month on it I started to unknowingly wake and take at least one (or more???) during the night. One morning I awoke to find about half my bottle of pills spilled on the floor by my bed. Another time I awoke to find an empty drink glass beside my bed. Apparently I had got up and mixed a drink (maybe more than one???) . . . SCARY STUFF! No more Ambien for me, EVER."
