I'm 8 days out and put isopure in everything. It's not bad and 27g of protein a scoop. You can mix it with anything. Just heat your warm foods first and then add it in or it looks like a science project gone bad.
My NUT lets me use it. I mix it with water and sip. She said it's great to help prevent dehydration and better than drinking low cal Gatorade with the sweeteners in it. Just not a lot. 1-2 tbsp per 3/4 cup water.
