John, how tragic. I am so sorry about your loss. It is good you were aware of her meds as much as you could be. I hear stories about how much people have been helped by these drugs, so I never toss the whole thing. But the variables are so compelling.
The drugs can do a world of good. But they can also doa world of harm. The doctors need to do more than jsut prescribe the drugs, Tehy need better diagnosis (what is the problem) and much better follow up. (If I can ask, please keep myself and my 5yo daughter in your prayers. It's been 8 weeks and we are still trying to get over the shock of it and get back to living a normal life like my wife would have wanted)
I'm a firm believer in better living through chemistry. However, I do take a holistic approach -- I'd never suggest fighting a way using just one weapon. And not any single thing will work for every person.
