Hi there, welcome to PC.
Is your husband taking a mood stabilizer medication?
That is the first thing important in keeping episodic behaviour under control, thus leading what most of us would consider a "normal" life.
Proper meds.,commitment to treatment plan and pdoc visits,learning more about the disorder,patience, and understanding, all lead to success.
Takes time but is all worth every second.
Bipolar disorder, as well as many other disorders are not "death sentences", there are more medications today than yrs ago. and a lot more research has been devoted to this area of the sciences, and still being done.
So there is better choices than years ago.
A person can also have more than one disorder at the same time, and now in today's times they can be treated at the same time. Sooooooooooooo, my advice is to keep faith, never give up,even when some dark days can creep up on you,keep in mind they shall pass, just stick with your meds and keep in contact with pdoc and/or T.
Take care now,
DE
