Ambien is strong in itself and has random potential to cause a wide variety of reactions. I have seen several people react totally different from it.
I was prescribed Ambien for a legitimate sleeping disorder. It was the worst medication I have ever taken. I remember taking it, as prescribed and a very low dose then becoming dizzy and disoriented. I felt drunk but I wasn't and then I blacked out. I woke up 2-days later and was told by my ex that I was out of control. He had found me 'sleepwalking', wandering around our apartment complex, knocking on neighbors doors... I even drove my car to the convenience store to buy hot dogs and I remember NOTHING. I also had the worst hangover I've ever experienced which lasted 2 to 3-days after I woke up. I had nothing else in my system. Was later prescribed Lunesta and the same thing occurred.
My ex also took it one night. It put him to sleep relatively fast but not fast enough as about 10-minutes before he fell asleep he became very violent, screaming, breaking furniture, punching holes in the wall, acting like an ass until he literally collapsed and passed out. I left him on the floor and he woke up feeling fine the next morning. He did not experience a hangover but he did not have any memory of punching holes in our bedroom walls or breaking our TV. I do not know if he had taken anything else with the Ambien.
Others I know who have taken the drug either say it puts them straight to sleep or it causes them to become restless and unable to sleep. I work in the health care industry and in all honesty, the percentage of individuals who do claim to have euphoric feelings or hallucinations is minimal.
If you choose to take this drug please have someone with you until you know how it will effect you.
