Wobenzyme is a good choice because it contains Trypsin and Chymotrypsin but keep in mind you need to take it in large doses. At least 10 tablets 3 times a day on an empty stomach with a large glass of water. Do not take it with food. I've read of people taking up to 90 tablets a day. Buy the 800 count bottle. www.myhealthpro.com has a decent price on it. Also, you might try and find a good QXCI practitioner.
