We found out in Oct/Nov my SO has both Crohns disease and Ulcerative Colitis. He's taking 4000mg of Pentasa a day, but lately he's having constant flares that are getting progressively worse. Yesterday he got sick and puked up things he had eaten like 3 days before.

Obviously Im making him call his dr Monday morning, but any tips in the mean time?
