Wow, I'd never even heard of this Guaifinisen Diet, so I Googled it and did find a Dr. Dantini in Ormond, Florida, who I think wrote the book. It does sound promising, and I do lean in favour of some kind of viral cause. But, like you, if a diet is sooooo restrictive, unless you have a personal chef, it's pretty difficult! I find with a lot of these diets, too, that they include foods that I have intolerances to (IBS!!) and/or are inflammatory. It all just becomes too overwhelming and exhausting when you're just doing your best to get out of bed and function on some level every day! The other red flag for me is a doctor's site that personally sell send-away tests, their own additional supplements, etc., etc. ...I guess that's what impressed me with Dr. Bested practice -- it's totally professional; you're simply provided with the information and decide yourself what direction you take, whether it's strictly 'western' medical (which is part of Universal Healthcare in Canada) or more alternative. In that case NDs work in her practice (but are paid separately on a sliding scale) and they will supply any tests and sell supplements (not their own) that they have researched stringently and also offer at a cheaper price for low-income patients. Her book is to reach people who are more housebound. She's really in the business of helping people in pain -- no profit here. (It's the most modest strip mall office, and I've often seen her mopping the floors herself near closing time!) I'm telling you, they broke the mould with this lady. It should be a medical model!
All that said, I believe everyone's an individual and, since they STILL don't know what the true cause is yet, why not try everything that's out there? Hopefully, something will eventually stick. ..A girlfriend of mine went the totally natural route, cutting out all the "bad" whites (sugar, flour, dairy), she exercises, uses infrared saunas, etc., and swears she hasn't had a flare-up in years! ...But I'm no martyr, so the more balanced approach is more my style.
One day I might even try organizing a walking group for people with chronic pain issues -- it can get lonely out there!
Anyway, Karen, I do hope Dr. Bested's book is of some help, though you could probably write your own, I'm sure!
Fibromyalgia, CFS, possible CSS, Chronic Depression/Anxiety Disorder, Agoraphobia, PTSD ... But they're all connected & I'm working on them all - I will prevail!
