I have been taking Zolpidem long term and it helps. You build up a tolerance, but it does continue to help. The generic version for Ambien is Zolpidem, which is inexpensive. You may want to look at joining GoodRx. It is inexpensive to join and Zolpidem is about $5 per month

It works for me also. I take it very infrequently though

The normal dose is 10 mg for men and 5 for women. You Must Take on an empty stomach. When I first started, I got 6-8 hours sleep. Now after many years, it takes me longer to small asleep. If I wake up during the night, I have trouble going back to sleep.

Good luck

Zolpidem is generic for Ambien. Zolpidem does not work well for many people including me. It's frustrating to take it for insomnia and then lay awake all night get good sleep with ambien.
