I was taking ambien and did well for 6 months then it was taking longer to get to sleep. I ran out now and the doc put me on trazodone and I took just 1 50 mg and did was horrible. It took hours to get to sleep and woke up many times, and the next day I was in and out of naps all day long. It took over 24 hours for me to feel normal and not be dizzy and headaches and other problems. I still have 29 pills but I don't want to use them.
