The morning I stopped the Prednizone I collapsed on the floor and was in and out of consciousness. My son called my husband at work and told him to come home quick. I came to and had terrible stomach pain. In the weeks before I had been suffering from a lot of gas pain, possibly due to the Plaquenil. A friend with RA advised me to start drinking Mylanta which helped tremendously. I have to eat frequently and stay away from carbonated drinks or I’m in a lot of pain.
