Hi Mazza, Sorry to hear you've been crook! I've been taking enzymes since about 6weeks after my whipples and even tho they are non addictive,I couldn't live without them! Before starting on them,I would get very ill about 15mins after eating.Severe pain and nausea.Also cramping and constipation.When I told my oncologist she prescribed the creon (enzymes)and the symptoms virtually dissappeared sraight away.The tablets do the job our pancreas isn't in the digestion process! Hope that helps a bit,good luck and I hope you feeling better soon,Margro
