I have taken Ambien 10 mg off and on. First I got headaches and stopped taking it and then I got a white noise machine which helped for a while. Then I started back on Ambien after taking numerous other insomnia medicines which didn’t work. Then Ambien just stopped working altogether. Went off again on Ambien and stayed awake almost every night until lack of sleep started really affecting my general health in other areas. Went back on Ambien and it started to work again and now I am addicted to it to go to sleep. I also take Xanax just to relax but I don’t take it with Ambien. By the way, the Ambien affected my memory. I can’t take melatonin because I have symptoms of a hangover the whole next day. So I had to choose between never sleeping or my memory. I chose the Ambien. Seems like no doctor I have gone to can help me. They throw their hands up in the air with no solution. These are the decisions a 73 year old person must make sometimes in their life. At least my anxiety has subsided for a while.
