I had been fighting this problem for about 20 to 30 years.Then I found a website on the internet for a cure program called Lactagen.I was desperate so I tried it.The treatment takes 35 days.At the end of the treatment I was really scared to drink the glasses of regular milk that they tell you to drink.Because before I went through this program any kind of milk product would cause me to have extreme diarrea and vomiting.I have been off the program for 6 monthes now and I can still consume any dairy products that I want to with no ill effects.Icecream,milk,cottage cheese,yogurt,butter,whipped cream.You name it,I can eat it now.The program costs about $150,but when you order it.You only have to pay shipping and handling and you can make three seperate payments when you do start paying on it after 30 days.Just yesterday I had two milk shakes and a bowl of icecream with no problems.If you would like to try this program email me because I can get you 15% off on the cost of this program with my name and a coupon code.
