HI-
I know my sister used this along with Ensure Plus. I don't think she had any reaction to it. I think she did 3 cans of this and 3 of the Ensure when she was at your stage along with water. She also tried Carnation VHC- which I hear is great, but it sat in her tummy like lead- she was very thin at that time. Good luck- Penny had 5 or 6 weeks chemo along with the 38 IMRT's.
