Comment:
I was reading some of the other reviews, about vomiting after taking a pill. If you are highly lactose intolerant, 1 pill will be OK for A PIECE of cake with milk in it or the frosting. If you are only slightly intolerant, 1 pill will be OK for a meal of pizza OR a serving of icecream. It's not magic; it all depends on what your body produces on it's own and/or how allergic/intolerant you ... Show Full Comment

Comment:
I used this product for months (not daily), and I was finally able to enjoy dairy again. I was so pleased! But in the last two weeks, I have experienced the terrible side effects others had mentioned, namely vomiting. It only happens when I take the pills, so it's not some stomach bug. Looks like my dairy days are over -- again.
