FYI, in the future... I believe you can appeal multiple times. So even if you get rejected on an appeal, you can still appeal again.

I know sometimes insurance companies want you to prove that there is no similar type of med you could try. (They want you to try cheaper options first, which I suppose is fair.) So if you appeal, they can reject you if they think there is a similar but cheaper med that you didn't try. Then you can appeal again, arguing that you've been taking it for X amount of time and that going off will destabilize you.

So if you get rejected once, you can keep making appeals.
