For some people Ambien sleeping pills are better than Sonata Sleeping Pills.
In some people the Ambien works about 3 times better than Sonata and keeps the person asleep much longer than
Sonata.
For me the Sonata tends to work much better than Ambien did for me.
I used to take Ambien but found it didn't work as good so my doctor prescribed me Sonata to try and it seems to work much better.
The Sonata puts me to sleep within about 10 to 20 minutes of laying down in bed and the Ambien seemed to take 30 to 40 minutes.
All peoples bodies are different and some medicines work better for one person than they do for other people.
