I'm sorry I don't seem very sympathetic in refusing to write a letter to your insurance company about the drug. Honestly, this stuff ain't cheap, and you should appreciate that your company is willing to cover it for you at all.
The 30mg and 60mg pills cost about the same per pill. So taking two of the 30mg each night, instead of one 60mg, basically doubles the price. And I really don't have a good reason to tell your insurance that they should pay the higher cost.
There might be medical reasons SOME people need this, but "because I like the cute blue & white 30mg, and not the ugly blue & green 60mg" is not one of them.
I also appreciate that blue & white are the colors of your alma mater, but again, I don't think your insurance company is going to feel that justifies them paying twice as much for your pills.
And for once I agree with them.
