You know, even the people that Ive dealt with who use medication exclusively to control Bipolar symptoms really dont have that much success. It takes some real dedication from them to decide that they dont want to be sick anymore, and a really good therapist to provide some cognitive behavioral therapy.
If I were you, I would also start learning as much as you can about this, there is some evidence that it can be inherited, so you could start looking out for it in your kid, and be better equipped to help him if it does manifest. Not to mention being in a place to help your W more effectively.
I guess I gave the wrong finger to the wrong man...
