TMI Lactose Intolerance

It sucks being lactose intolerant. I've just been avoiding dairy because I didn't feel like buying the lactaid pills. I bought the pills the other day and I had some cheese pizza with the pill as the directions say and my stomach has been rumbling. Tmi but I've pooped out about a gallon of poop. I feel like I might have to go again tummy is still sore. Has anyone had this happen while taking the lactaid pill? I'm just glad I made it home in time or I could've shit my pants. :(
