... to gastric issues related to malabsorption due to gastric bypass surgery. I have extreme pain due to Fibromyalgia and Chronic Fatigue Syndrome/ME among other things. My doc started me at 4mg 4 x's a day but it only takes the edge off. I experimented with taking 8mg 4x's a day and that is much more helpful. But need to call Dr to ask for a new script and wondering what dosage I should ask for?
