if you dont have CF creon will not help you gain weight. it isnt a weight gain product, it is an enzyme. people with cf dont produce their own enzymes so have to take artificial ones in order to break down their food. you dont have CF, therefore you produce your own enzymes, so dont need to take creon.
i seriously advise going to see a doctor about healthy and sensible ways of gaining weight, dont just take random drugs! best of luck <img src="i/expressions/face-icon-small-smile.gif" border="0">
