Thanks for the suggestion. I have no stomach upset problems with glutamine or glycine at high doses. I initially had problems with the insulin release and subsequent drop in blood sugar. It's manageable now. I've learned not to breathe deep and walk around for a while before I stretch out so I don't get a headache and dizziness any more.
I had tried to use blender bottles before but I needed at least 48 oz of water to get the mixture to a palatable level.
