Nausea is almost a daily thing, always accompanied by lightheadedness. The diarrhea was awful the first year, liquidly, and no warning cramps. I was afraid to leave the house. It's gotten better, but I still have days when I spend too much time on the toilet. I did lose 26 lbs., which was needed. I could still lose 40 more to make my doctor happy. I do take Culturelle probiotics daily, Pepcid, and Zyrtec too. I think it was the addition of the Pepcid that the doctor prescribed when she saw I was getting rashes and diagnosed with Mast Cell Activation Syndrome. She said the Pepcid has a different type of antihistamine that would boost the antihistamine in the Zyrtec. I just know that I cook meals for my family my stomach will clench and refuse to let me eat. Oatmeal, Bone Broth, and Chobani Yogurts are a my fall backs when it gets bad.
