Yep - I've been following a similar diet (GAPS) to improve some health issues and found that the first few weeks were tough because of sugar/carb withdrawal symptoms but it improved a lot after that. I'd recommend the book Nourishing Traditions for anyone wanting to keep eating some carbs. It's based on the Specific Carbohydrate Diet which it's my aim to transition to eventually as it's a bit more relaxed about grains/pulses/dairy when prepared correctly.
