insomnia
"Very interesting drug. I was prescribed Zolpidem by my psychiatrist but found that it did not work (later determined because of other psychological problems) however I still took it every night. I found that I started doing things I would never do normally. I went for walks at 3:00 am, fully cognitive, came home put my shoes away, hung up my clothes, and watched TV for a few hours. I felt perfectly normal, but my wife started questioning me about what I was saying to her (never violent). She said that my conversations always made sense, but they were so out of the blue. Sometimes I remembered them, sometimes I didn't. If this drug does not work immediately, don't take it."
