Ambien Addiction - Help

My grandmother has been feeling under the weather the last few months.

Headaches (dizziness, and pain) and stomach aches and insomnia.

Probably all related. (insomnia causes headaches, or vice versa)

Doctors did not find anything strange during tests, etc.

So the doctor gave her ambien to help her sleep. (and other stuff for
the pain)

I just found out she has been taking like 2-3 a day!

She takes 1 pill and sleeps for about 4-5 hours, then wakes up, and I
think she takes another one to sleep.

She keeps taking it because she cant fall asleep otherwise.

So she wont stop taking the pills.
Any advice to help her get off the pills?  (alternatives, etc)

Thanks!
