CFS and dietary B vitamins

I am mentioning a dietary change that has helped me; I don't know how it may have affected others. More than 30 years ago, I first had diagnoses of fibromyalgia and CFS. I had only a little improvement with taking sleep medications. Later, with a sleep study, I also had a diagnosis of a variant of restless leg syndrome. After a few years of the continuing muscular pain and stiffness, fatigue, and 'brain fog,' I began investigating the effects of dietary manipulation. After trying various diet changes, I have arrived at the conclusion that, for me, restriction of the 'energy' B vitamins, especially late in the day, is the optimal diet. When I have little intake of foods with these vitamins, I find that I do not awaken with as much fatigue and 'hangover' or with some of the bedcovers on the floor. These energy vitamins seem to promote a disturbed sleep pattern. In the late afternoon and evening, I restrict foods with flour, cereal, beans, nuts and others with labels that indicate even moderate B vitamin (particularly thiamin, riboflavin, niacin) content. I have at times used this finding to my advantage by consuming such foods, and multivitamin tabs, in mornings to gain energy during the day and without disturbing sleep.
