Have you done a very thorough bowel and parasite cleanse?
I have had chronic fatigue for the past 20yrs. It is slowly going away. As was mentioned I was tested for a gluten and dairy intolerance. Two yrs ago I completely changed my diet and gave up all processed food, dairy, gluten and sugar. Then I did a very intensive parasite and Bowel Cleanse for about 9 months. I was loaded with parasites. I still take a daily maintenance. I have also completed 9 liver flushes.
I now put in a full day plus excercise. It is very exciting when the body heals.
Oh I also got rid of bipolar, migraines, fibro and chronic constipation. I was on tons of meds for over 15 yrs. I haven't even taken an aspirin in a very long time.
