Protein Drink With Sugar or Artificial Sweetners?

I am trying to find a high protein drink or soft serve that has no artificial sweetners or suger in them. Can you help me?

The artificial sweetners cause colon spasms according in the friend I am looking for this. Has anyone had this problem with artificial sweetners?

On one of the blogs I read, somebody recommended for custom protein mix. It looks like they can do totally unsweetened mixes. Obviously you’ll want to do more checking before placing an order, but that at least gives you a place to start.
