First Post - ADHD Wife

Alright, this is going to be a bit of a ramble, but, painting the picture.

husband and wife 38/37 - 4 kids (10 (also ADHd), 8, 5, 1) - ADHD wife

So, I'm at a little bit of a loss here. My wife was diagnosed about 2 years w/ ADHD which was no surprise to either of us. It was a "yeah, that makes sense" type of diagnosis. 
 
jumping right in; the rage and anger are absolutely out of control. She's tried a few meds, vyvanse worked for a while, then became too expensive, so about a month ago doc prescribed aderral xr, and it worked, but, she's also nursing and the correlation between her starting that and our babies sleep was a direct correlation. So, she stopped and the rage wowowow! How long does this last?

ok, this isn't as eloquent as I would've liked it to be, but, my first post. I'm hoping to learn of others experiences with this.
