Hey Penny, I am NOT an Expert, (Matter of fact, as a husband I am remind that I don't know NUTHIN), But I am 5.5 years PostOp, and never supplimented with anything other than (un-named) chldrens cartoon vitamins from "Bedrock" (Hint Hint, wink wink) I will say though that after a very careful medically technical dicussion with my doctor we both settled on the FACTUAL decision that both "Wilma and Betty" were equally "hotties", and should primarily seperate them from the other characters. AGAIN let me remind you that I am NOT an EXPERT, so Fuhgeddaboudit---Craig T 5.5 years PostOp
