More Diet Changes

I've been doing the THM (Total Health Makeover - mostly vegetarian, dairy-free, sugar-free, and, for me, wheat-free) diet for almost two months, starting the day with a piece of fruit, then a bowl of oats mixed with granola and soy milk, and doing lots of salads with beans and grains. And Luna bars. And I had the worst month I've ever had - constantly bone-tired, no stamina, napping every day and going to bed earlier than usual, low blood pressure so I'd feel woozy when standing, visual auras, headaches, blood sugar drops, on and off sore throat, chills, and my head felt puffy so that my eyes would't fully open. All of this for a MONTH! I wondered if I had a virus.

The day before yesterday, I woke up exhausted, foggy and with a headache as usual. Instead of granola, I made a green-green-green smoothie with one apple and lots and lots of spinach and lettuce. It tasted tolerable, but not sweet. And within an hour, the headache and fogginess were gone and I didn't feel exhausted anymore. I've felt a lot better the past three days doing dark green smoothies, salads and a small serving of beans and grains late at night.

So now I'm looking at The PH Diet, which is mostly raw, lots of greens, but almost no fruit. Lots of green smoothies, salads and vegetables with a little other healthy food added in. It could be that too many grains (granola, millet, rice) is too high in carbs? Or, one thing I haven't considered, maybe the gluten in the oat-based granola isn't agreeing with me?
