Ok liten VERY carefully! I'm 100% lactose intolerant....I have been since birth. I was even tested for it at age 4! Yeah...not a good test to take I do not recommend it!
take simethicone (GAS X or oen of those meds.) Take a double dose NOW...and take a regular dose again in about an hour or 2.
YOGURT...with live cultures, or if you happen to thave the capsules iwth the cultures that's even better. But a cup of yogurt, per hour for at least the next 3 hours. The bacteria actually feeds off the lactose breaking it down similar to how the enzyme would do. Take 2 lactaid tablets now. Might not help much, but it won't hurt either.
Trust me. I've been hospitalized over cheese popcorn. I have learned the way lol. and ALWAYS keep lactaid-----or the generic walmart brand. I take 2 with each meal.
Oh and the 100% lactaid milk mixed iwth chocolate syrup is YUMMY and works. No pills needed
Oh side note: all the simethicone will break up the gas, and most likey give you a bit of diarrhea for about 2 or 3 hours....but it gets it out and over faster and you'll be ever so thankful!
