Hi Lizzie, I've been trying to get my insurance co to cover the Vsl ds, no luck, my drs office told me to go to this website (Nord.org) It's an organization for rare disorders, they help people with problems, one of which is helping with Rx, I'm in the process right now, waiting on paper work. Give it a shot. The phone number is 203-744-0100 ext 266. Cathy. All the Glory is Gods
