Have other Freepers noticed a change in the taste of diet Mountain Dew? Yesterday, I bought some at my local 7-11 and noticed the change. It was so bad that I poured it out on the grass. I went to another 7-11 and bought a new diet Mountain Dew. This one was OK. This morning I opened a bottle that I bought at our local supermarket and again that same terrible bubblegum taste! Yuck! So?...Does anyone have news on whether or not the formula has changed? If it has, then I am done with Mountain Dew. It is now too...
