MIL is borderline diabetic so we gravitate towards those things. Then get home and find out they added sucralose and/or acesulfame artificial sweeteners. DH and I can both taste the difference and don't like it.
The worst thing we have gotten hold of so far is Lipton's Southern Sweet tea tea bags. Ick, ick, ick! Being southerners we DO like our sweet iced tea, but we like it sweetened with REAL sugar during the preparation. We keep a gallon pitcher of sweet tea in the fridge at all times. MIL has given up drinking tea and sticks with coffee or water.
