insomnia
"The first time I tried Ambien, I was told I was sleep walking with nothing on but a t-shirt.  I dont remember this at all, but was told I refused to put on my pajama pants or underwear.  The 2nd time, a couple yrs later, I  took a generic. This time I remembered microwaving a plate in the middle of the night, piling a mountain of random foods that should never be seen on same plate. I walked out my front door, locking myself out. Wearing nothing but a tank top and underwear, holding that ridiculous plate. I thought the door bell wasn't working, as I pressed and pressed for a long time. My neighbor came out- rang it on 1st try."
