Greenstone Xanex?

Hi,

Does anyone know if Greenstone xanex is in the process of being discontinued?

I was taking Dava, which sold to Par, for some years. Now I have to switch again because it's being discontinued. I'm trying to find one that is perhaps going to be around.

I had a bad experience with Brekenridge (I think that's the name) a couple years ago.

Any recommendations of brands that aren't horrible and hopefully won't be discontinued would be appreciated. Thanks so much.
