I used to take all kinds of ritalin, welbutrin, and worse. Went Primal, and it began to help, but I was still down a lot. Increased my meat intake as part of my dietary experimentation and WOW, I felt amazing! Then I discovered liver. I ate a pound of it per week for six weeks before my body said to slow down. I was vitamin deficient in every possible way! Liver has consistently dampened my cravings, self-abuse, guilt, and many other ways of misery. I frickin' DARE you to feel sad or depressed for the three or four days after eating a pound of liver, cooked medium-rare, once your body is packed with existing liver nutrients. Make sure it's still bloody and soft inside. Only get grass-fed liver from a trusted local source, if possible. You can buy an ENTIRE liver for about $25.00, so no excuses.
If you like being sad and mopey, and letting the voice in your head have its way, then DON'T eat liver.
And vitamin D, that makes a huge difference, too.
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.
