I identify as alcoholic, but among my addictions was ambien. My story is similar to yours, taking it during the day to escape, etc... I have talked with people that used up to 20 (twenty) 10 mg tablets a day!!
I used trazadone for a week or so to get back into a normal sleeping pattern. That was after I stopped cold turkey and didn't sleep for about 4 or 5 days. After 2-3 weeks I was sleeping OK without anything. And after 1-2 months... sleeping normally.
I am blessed, after 14.5 months of being clean and sober, I sleep very well. It's almost a miracle.
You are NOT alone, I have met several people who dealt with ambien addiction. Welcome
