I was taking Ambien for over 20 years. I have slowly tapered off until i was at 2.5 mg. I did this over 2 months decreasing my dosage weekly. I had a lot of sleepless nights with pain. I am 77 years old. At 2.5 mg I added 1mg of liquid melatonin 3 hours before I went to bed. It has been working! My physiatrist(a PT MD) told me to try this because I have been waking up foggy.
