>> I started adding in some dairy, then eggs, and then sugar (in moderation)
Watch the dairy. Especially if it is milk mixed with sugar.. I find strange reactions to dairy can creep up. such as eye pain (uveitis/iritis), foot pain, hand pain etc. Not necessarily AS per se but related.
Yoghurt, sour cream or any cultured milk is of course the safest. I can safely mix yoghurt with honey (monosaccharide is safer for me, quicker digestion).
Too much chocolate and bladder issues can arise (sugar?).
Going a bit off topic ... Recently found eating *large* amounts of leafy greens alleviates this bladder issue, eg: baby spinach leaves. So good to be rid of this problem, and have a nice natural solution. I suggest a no starch Caesar salad if anyone else has this.
