Cure for Lactose Intolerance?

My mother tried Lactagen and has been cured of Lactose Intolerance for over 10 years now. I myself am on day 30 of the program and can’t believe I’ll be rid of all the LI problems in my life. Is this a miracle or what? Anybody else been cured from Lactagen? It’s funny because I used to see the TV ads but I haven’t seen them in a long time.
