I saw a holistic doctor through my many regular ones who suggested this a long with many other dietary and supplement changes. I currently see a nutritionits but for seperate issues but am hoping it will help with this too. The thoughts I have around diet in whole is that it will take time to see any changes and I know for myself I get frustrated. I am trying though and also with the thought that it may help to prevent other problems as I feel my immune system since I have developed rsd with infections so on is bad. Year ago before I developed this I cut out caffeine and at first I felt horrid from my body being so used to it but after a month or so I felt more energetic,calmers,better sleep/digestion.
