I know about the headaches, me too!!!
I have found myself to spend 7 hrs doing research on diabetes, thyroid, B12 and so many other things. When I get frustrated with information overload, which happens...I make myself a "course of action" then after reading I change it, then change it again, then finally I know its time to walk away. I stop, pray, and walk away for a day or more. Come back and start again.
It's still the most productive time since I have helped myself with my own research more than the doctors have.
And it never ends. lol. One thing always leads to another. It's like we are on the search for a treasure, ie
ur health, and constantly looking at a map, finding clues, and every time we find something it leads to something else. lol
