Not awful funky, just... Let me put it this way. As someone who's had IBS off and on for years, the resolution of that problem instantly a day or two after starting paleo was a huge reason to stick with it. A miracle, really.
The way I explained it to people was to say that my "digestion" was sooooo much better. And so it went for more than six months. Me and my gut, finally BFFs.
Well, for some reason, suddenly my digestion is soooo not better. And it sucks.
Fortunately, Melissa at Hunt, Gather, Love, (www.huntgatherlove.com), has broken this ground already. She often discusses IBS issues and has written about how non-paleo foods like white rice seem to help people still - or suddenly - symptomatic. I bought a bag of basmati tonight. We'll see if it works for me, too.
Still, the whole thing is such a mystery. How could all the very same foods that have worked so well since Feb. 1 suddenly have turned against me?
Fortunately, now I'm far enough into this way of eating that I have many more reasons to stick with paleo than just IBS relief: great blood pressure, continued relief from RA pain, steady energy.
I love eating protein and veggies, it's simple and logical and works in many ways for me. I have to believe my gut will come back around, too.
