Every couple bottles I end up with a big blob of undissolved powder at the bottom of the bottle. I'm just using two scoops in a regular bike bottle, so I don't think I'm over saturating. I like this stuff otherwise, but when this happens I feel like I'm missing out on most of the nutrition. Does this happen to anyone else, any solutions? I haven't had this issue with other mixes I've used, but I like how un-sweet this stuff is, so I'd like to keep using it if I can solve this problem.
