lactose intolerance
"After not having many issues with any dairy other than ice cream, I decided to try lactaid in order to be able to enjoy the delicious treat of vanilla ice cream once more...but I regret everything now. Not only did it not do Jack squat, but my symptoms of lactose intolerance are even worse now. Usually I can get away with just a little bit of gas and I'm fine but now I have nausea, diarrhea, gas, and bloating. Worst decision ever!!! This product deserves negative stars!!!"
