Yesterday I started Digestive Enzymes which my M.E. doctor felt I needed to take. They are 'Nutritionals' brand and contain Pancreatin, Pepsin, Ox Bile, Papain and Alpha Amylase. However after taking my morning dose (2 tablets) today I have been so terribly nauseous. I'm sure this must be the enzymes. Tomorrow I will wait and see how I'm feeling and then may take only one tablet and from there build up more slowly. Anyone else had this side effect and if so, how long did it last?
