Treatment cost

I'm on Roche's Pegaysys and Copegus, and finding it very expensive.  My supplemental insurance provided a little prescription drug coverage ($250 deductible, then 50% co-pay to a limit of $1260 per YEAR)  That will only cover expenses for a very short time.  Did someone post earlier about help with the cost?    I would appreciate any feedback.
