Your kidding me, the cost of this drug is pocket change.
Stop caring what anyone but your doctor and reviewed studies says about what you treat your most valuable asset with and life will get easier. Every time the RX pad comes out, tell him/her you are paying in cash at the walgreens and will only get the perscription filled with a generic or a $3/day drug. You will get the RX hits of the 1980s that are generic, cheap, in stock, widely tested and have near zero marketing cost per tablet.

The number of people who bitch about lifesaving and life extending drugs at $7/day and sit in blue states paying property taxes in excess of $1000/mo ($33/day) must be at least 35% of the elders from across the US.
If drugs make your life to expensive to live, look at your tax man and call a moving truck.
Excellent advice!
