I also had issues with "dumping" the first few weeks, but mine happened with the sweet protein shakes. I found Syntrax Nectar, fuzzy navel and drank that mixed with Crystal light lemonade and ice. That was refreshing for me and didn't give me the heavy feeling that the milk based protein drinks did and I tolerated the taste so much better also. SF popsicles were my favorites and still are. Good luck.
