no, i don't feel wonky after eating fruit.
i've been avoiding yams and sweet potatoes because i thought you were supposed to avoid them on the paleo diet. good news for me though because i love 'em!
and to answer your question, no, it's not a shaky and irritable kind of hunger, which is how i used to feel when i was eating sugar. it's more like, damn, i just stuffed myself 10 minutes ago and i'm hungry again.
