Stevia? My wife has much stronger bitter receptors than most people (including me, and I thought mine were strong) but Stevia is fine for her. Aspartame, though, she absolutely despises. I think they're both fine, but I can pick up a hint of what she dislikes from Aspartame. Sucralose is also fine for both of us.
