Sorry, but I don't know anything about this specific drug, Kenny.
Most of the sleep aids and anti depressants have some sort of a side effect that is unwanted. The only one that seems fairly innoccuous is elavil (amytriptaline) which also has an effect on brain chemsitry which helps prevent migraines. (I've taken it before bed for many years now and it really has been effective for that purpose).
Anti-anxiety medications and sleep aids like Ambien all seem to have some side effects that CAN be unpleasant to some and not to others. You often have to try a few to find one that agrees with you. Ambien can cause you to do some far out things in your sleep. Like: get up and drive to the store on an impulse, buy a ton of junk food, eat it all and go back to sleep. (my brother actually did that). Ambien is strange stuff....
If your wife was ever a weed smoker, I personally believe that it is one the very best anti-depressants on Earth for some individuals. Others may not find it acceptable for many reasons, especially the legal aspects. I'm not sure where you fit into that issue....
Counseling can be a great approach to obtaining mental keys to derail anxiety when it starts. There are several mechanisms that a trained professional can provide to short circuit the attacks with one's own will power, mental acuities and just sheer emotional strength to derail anxiety before it takes a foothold....
I personally have dealt with attacks of depression and axiety. I approach them both very differently:
With depression, I get up and walk away from it... I bury myself in some chore, act of goodwill, diversion- anything I can to distract my mind from the cloud of depression.... Whatever it takes to simply distance my mind from whatever is attacking me..... Most depression is a result of a chemical hair trigger in the brain that sudden adversity (stimuli) can set off..... The distraction just acts like a reset button button for my brain....
With anxiety (fear), I do something that is just plain reckless. I embrace the pain.... I run towards it and persue it- as if to say, "fine, bring it on- I don't give a shit...." which ultimately shorts out the system becasue I'm not resisting it.. It's like saying, "is that all you've got...?" . The act of facing it head-on forces me to confront the demon and ultimately brings me to the realization that it's my own fear that's the real enemy... And it isn't such a big deal afterall.... It's just a fake goblin in my head.
Sorry to ramble so much..... I hope something in there has (in some way) been helpful.
God bless.....
