Do you actually think these patients didn't "keep looking for answers", some of them for decades? The answers weren't found and then they got on Ambien, which allowed them to at least sleep. Some of the Ambien Reviews describe exactly that.
I encourage people to try Ambien while their doctor is "looking for answers". When Ambien works, it is with far less side effects than hijacking "solutions" like antidepressants, anti-psychotics, anti-histamines, and hormones. Ambien has nothing to do with the horror stories on ill informed sites and claims by some medics. The negative reviews of it are mostly that it didn't work for them.
