<<Disclaimer: Verify this information before applying it to your situation.>> Hi, I'd like to know how anyone taking fosamax has done on it AND if they had any problems or reactions to it. My doc wants me on it but I understand it can cause gastrointestinal irritation. I react to gluten with neurological symptoms and I'm also very sensitive to many gf foods, meds and vitamins so I'm a little nervous about taking something that is known to cause irritation. I'd appreciate any experiences you can share. Patti
