Thank you for the feedback, it's nice to read! :D

Sounds like you're eating healthier than 90 % of people. But the reason why you feel bad when eating 100 % fruit or 100 % raw is because those foods are so clean from toxins that your body can detox and flush out toxins more quickly and effective. That's why you can't start with 100 % fruit. You will last a week or so because you start detoxing so deeply that you start feeling very sick.

I recommend you to read the book Mucusless Diet Healing System by Arnold Ehret. It's all explained in there.
