Delzicol in short supply; pharmacy can't fill it

Does anyone else here take Delzicol? I just got a letter in the mail from CVS Caremark (mail-order pharmacy) saying it is in short supply and they can't get it from the manufacturer. They told me to ask my doctor to prescribe me something else! I've taken Asacol and then Delzicol (which are the same thing, really) since diagnosis. I'm pretty sure it doesn't do anything for me anymore but maybe I'd be worse off of it. I still have a month or so's worth at home.

Give away medication? What??? I can't get my medication from my pharmacy. They sent a letter telling me it is in short supply. I wondered if anyone else on Delzicol had been dealing with the same thing. I've never experienced this before.
