felecia187 this is bast on my own experience until i figured this out , up until then i have had an allergy to milk , well now i know better , i can now drink all the chocolate milk i want no problem , and i can now drink more white milk then i use too , so what i discovered is that if you take 500 mg of vitamin C once a day you can drink more milk awesome simple right no more pain , this has been a pain in the butt because milk with people who are sensitive to it get hemorrhoids , cut back on the milk and take the pill , then you can gradually drink more milk , cure treatment call it what you want it works for me no more pain in the butt for over 15 years , so take the advise and enjoy
