Mark Hancer at Mayo Scottsdale listens to you and works with you to get to the bottom of your GI issues. When the typical approaches don't work (more meds), he thinks outside the box and suggested I try a pause in Metformin for 30 days. I was hesistant because I had been on this for 20+ years. I followed his suggestion and it changed my life. I could eat fiber again! Burping, bloating, abdominsl pain gone! I can sleep flat and don't have to take OTC antacids. Now just some nausea but significantly improved. Look for someone who will listen to you and think outside the box. Mark Hancer was that medical professional for me. I am so grateful to him for improving the quality of my life.
