It's funny that you mention the digesting/bloating because it's been hell today. Digestion seems okay (no gas etc) but I am definitely bloated. I will be reducing my meat servings to 6oz... Don't seem to be getting hungry as I should be. I also started a probiotic a couple days ago with the idea that it would help with the higher protein intake. I may also need to add digestive enzymes..
As far as my creatine and glutamine dose goes, I really just took Mike Arnolds template of 5g creatine and 10g glutamine in 2 separate shakes but went ahead and combined it into 1 shake which I sip on during my workout. I think I could get away with half the dose (as it seems like you were hinting as well) but at the same time, MA and Milos both have higher amounts of creatine in their protocols so I just went with it.
I've always done juice in my intra with another carb source for really no reason other than I wanted to. It used to be pineapple juice or whatever else I had, always pure so I could justify it as getting my fruits in lol... Only recently have I started using pomegranate juice due to its prostate health and heart health benefits as outlined by Dante Trudel. Here's a post where Dante talks about this
