For Lactose Intolerance "I have tried these pills twice. Once last week, and I got violently ill, vomiting for 5 hours straight, and then diarrhea about 4 hours later. The vomiting was so bad that I couldn’t hardly breathe in between. I got cold chills and was sweating profusely. It was absolutely awful. I tried again last night, not knowing what exactly caused the illness the first time. Same exact thing. No way will I ever take another one of these or suggest them to anyone."

For Lactose Intolerance "Two nights ago, I indulged in some ice cream and decided it would be a good idea to take 2 Lactaid pills with it. Wrong! Yesterday, I was sick as could be with multiple unpleasant bathroom visits, cramping, nausea, chills, etc. Apparently, based on the other reviews here, I was one of the luckier ones. Now, 48 hours later, I’m finally feeling like myself again. I threw away the rest of the package. Do yourself a favor and avoid these."

For Lactose Intolerance "This is the second time I used Lactaid. OMG, did I get sick! Within one hour of taking it, I was having diarrhea. Then came severe vomiting! Had no time to lift up my toilet seat! What a freakin' mess! I was so thirsty, but each time I drank water, back to hugging the toilet I went! Had chills and a low-grade fever. I have no idea why this reacted the way it did, but I will never take it again! PS. I finally discovered why I had gotten sick over my sister's house a month ago. Thought I had a 24-hour bug. But finding out today, it was the Lactaid she gave me!"
