Very sweet and aftertaste.
I so wanted this to be an answer for me. It is overly sweet when using a full scoop. The sweetener leaves a rather unpleasant aftertaste. It does taste like an oatmeal marshmallow pie. The first sip is really good. The more I drank the sweetener aftertaste got too strong to enjoy. The flavor is basically good, just that aftertaste that turned me off. On a positive note it did help me feel full for a long time. Next time I try it perhaps I will try a half scoop, maybe won't be too sweet.
