Have you tried applying for patient assistance and including a statement explaining you can't afford the medication despite having part d? I've done this successfully for years with a number of pharmaceutical companies. I feel like I got something through Sunovion this way but I can't remember what or when.

I just write a note that while I have Part D the copay for the medication is impossible when combined with the need to spend my limited income on things like housing, food, etc. And explain that this the ONLY med that has ever helped me with depression or asthma or whatever.

It's worth a try.
