I am a Diet Dr Pepper girl but I thought I'd give this a try. I have a terrible stomach ache after I drink it- cramping, etc. Anyone else have this issue? I'm pretty sure that the symptoms are from the Diet Coke Plus. I've never had this issue with soda before. I'm not eating anything different and if I don't drink it I'm fine. Hm.....so much for "healthy soda" I guess.
