I feel terrible! *TMI Warning!*

You may have a stomach bug, or your stomach may need more time to build up enough beneficial bacteria to properly digest nutrient dense whole foods. I would forego the oatmeal for awhile and switch breakfast to a raw shake made with raw milk kefir,bananas, 2 egg yolks, 1 tbs coconut oil, 1 tsp cod liver oil and some raw honey if it isn't sweet enough for you. The raw foods have their own enzymes and are less taxing on your body. I sometimes use frozen wild blueberries instead of the banana and I drink these shakes at least once per day. I would also take keifer before any snack or meal throughout the day.
I learned in NT that eating a bit of lactofermented veggies(sourkraut etc) along with meats, then ending the meal with a bit of the gelatinous bone broth is a great way to help your body digest the meal.
Also, it will take some time to normalize your body -- feeling poorly for a while can be a sign of detox.

Hmmm... well my NT sins the past week have been:

-last night had 1 white flour tortillia with raw honey (was having a massive sugar craving and dh was eating this)

-DH bought a nut mix at the store that i have been munching on that has some sugar coated nuts mixed in it, and I assume that the nuts haven't been soaked or anything - I am currently soaking some raw nuts

-Tuesday night we went out to a bar on a date and drank beer and ate fried bar food. Big no-no, but it was a blast.

I am racking my brain, but I think thats about it. Other than those sins, we have been eating really well. I haven't been marinating the meats overnight - more like 3-4 hours, and we are doing lots of veggies and some fruits. All organic.

I am going to ease off on the coconut a bit and see if it helps - I have been using it pretty liberally. I always hated coconut as a kid, maybe I knew instictively that it was a bit harsh on my system.

The raw butter is crazy good though... YUM!

Well, I didn't have extreme issues with NT eating when I started, but then I was eating pretty much a whole-foods-type diet to begin with. However, I did have trouble when I started consuming coconut oil. Pretty much the same as what you described. Once my body adjusted to the CO, however, I was fine. I think that it was cleaning out toxins or something. I trouble with raw milk when I first started drinking that again, too (I grew up drinking it, then quit when I went veg.). Between the raw milk and the CO, well, let's just say it wasn't pleasant!

I've been at this for about 15 months, and can say that I feel great, now. I think maybe the first 3 months (when I introduced pastured meats) were fine, then the middle 3 (when I introduced CO and raw milk) were kinda rough, and the last 9 have been great.

One thing that I found really helpful was to really cut back on grains, even properly prepared. That made a HUGE difference in my overall wellbeing. The other thing was to cut back on how much raw milk and CO I consumed, and gradually (I mean very gradually with the RM, not so slowly with CO) increase the amounts I was eating.

Btw, I've never had a problem with homemade yogurt or kefir. The culturing process makes them SO much easier for the body to assimilate.
