I've consulted 3 tax attorneys concerning her IRS issues and how they affect me. In addition, I'm a CPA. I'm very aware of the risks.
Maybe "popping ambien like chicklets" is extreme. She takes ambien nightly, and it's impossible for her sleep without it. That catches me as being extreme.
Then again (and the thing that makes me doubt myself), having never taken anything stronger than an asprin in my life, I'm not sure what a "normal" amount of drugs are (prescription or otherwise). It all seems extreme to me.
She doesn't have multiple doctors that I know of. I would see them on our health insurance statements, unless she's visiting multiple doctors and not using the insurance.
Thanks for all the replies, ya'll!
