Having been dealing with this for 10+ years, I would say I am a chronic sufferer.
Unless I missed something, how do you possibly carry ice with you if you are hiking, or doing anything else, without it melting. I've even tried a cooler but it melts. I live in south Florida.
Perhaps your lean body weight is a key to your success. What about those of us who are over ideal weight?
I agree about modern medicine -- what good is relieving symptoms? A cure is what we need for this.
I'm interested in learning more about the 'gut thing'. I did a little reading in Michael Murphy's books on Nutrition. But I would like to know more. I read that tomatoes, eggplant, peppers, mushrooms(?) are to be avoided for people with inflammatory issues. (The nightshade plants) Haven't tried it, but I do eat a lot of tomatoes, peppers and mushrooms....
I think I got lost on the connection between the Great Smokies Lab. And, yes, if you locate a doctor in southwest Florida, let me know. It's worth a shot.
Looking forward to hearing from you.
