I've not had a chance to read the book. I have read some of the blogs/info about it. I am grain free, unless I'm getting some from sources I'm unaware of - I've been amazed at the things hidden in foods. I have not tried going without the migraine med though. Honestly, I think I'd be too scared too! I've eliminated all my other known triggers for migraines and the one left I have know control over - storm fronts/systems. The topamax has never been an issue for me before and it has worked wonderfully for me, and now I am having to sort out if this side effect is from the med or something else. It's all too crazy! Ha!
