Hi, 2thebitterend, and welcome! I'm so glad you found us and joined the family. Much of what you talked about are things that happen with fibro...and also diabetes. I'm diabetic, too. I couldn't take Metformin either...did a number on my kidney function. But I now am on Glyburide and am doing nicely. Keeping the diabetes under control will help a lot. We do have a wonderful Diabetes forum on HealingWell, too!
Be sure to read Fibro 101...the second thread on the forum. There are links to good info about fibro and you will learn a lot there. Good starting links are called Symptoms, What Else Could It Be, and A Thorough Explanation of Fibromyalgia. You just might see yourself there.
I'm looking forward to getting to know you better. Don't hesitate to ask questions because we are here to help you. Hope to hear more from you soon.
