<<Disclaimer: Verify this information before applying it to your situation.>> My Dr. has just prescribed vivonex for me to drink (haven't got too many foods I can digest). Has anyone used it? What does it cost? My pharmacy says they don't know anything about it but it will cost me over $400.00 a case (120 packets). I am supposed to be drinking between 6-8 packets a day! Surely can't afford this if it is right. Anyone know about it? Thanks, Nancy in Texas
