I was a salad shooter at first. The problem is that your stomach has not fully acclimated to its new duties. It helps to cook your veggies well, chew thoroughly, and eat them with something else like meat. Also, you can probably cut back on leafy portions for awhile while your gut figures this all out. It took me about three months to stop shooting the salad. Again, I emphasize the cooking. Raw, it will fly through you and be of no nutritional value at this point. You might as well open the salad and dump it in the toilet at that rate. Perhaps try reintroducing raw greens a bit later on, and in moderation. You don't want all that oxalate, either.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
