Re: brain fog
If you and your son are experiencing the same problem, I'd also look at an environmental trigger. Has anything around you changed??? Did you shampoo carpets, have dental work, have extermination done, paint, is there mold growing....anything?
Also, as BOB says, diet is huge! Cleanse. Start with the colon, then do other organs (kidney, liver). Don't just start popping supplements...give up things. Eliminate sugar, white flour, etc.
Also, look at the "fog". When did it start...this year, last month? Ever have it when you were young? Is there anything emotionally you're trying to escape? It helped me to look at my fog and ask what purpose it served in my life. Then, I watched when it was there, and how I was feeling.
Keep on the path and keep the faith!
Hope this helps.
In good health,
Karen
