i introduced my bf to lactaid about a month ago since we discovered he was lactose intolerant. i really thought it would help considering he still loved to eat cheese and other lactose containing foods. at first, the lactaid seemed to be helping but just last week he took 3 extra strength lactaid pills because we were having chicken cordon bleu for dinner, he woke up 1 hour later with severe stomach pains and he was vomiting over and over. this lasted about 1.5-2hrs. i'm not lactose intolerant and didn't see the connection to the lactaid pills. we thought it was just from chicken cordon bleu because he had it before without the lactaid pills and he got sick from it too. today he took 2 extra strength lactaid pills and again, about an hour later he was feeling ill and was vomiting and experiencing diarrhea. we can now conclude it was the lactaid pills causing him all this pain. i feel so guilty for introducing him to these pills because i thought they would work. never again would i want to see him go through that much pain.
