Thanks so much for your comments, CHfather.
I wish others would try this as well and post. Also, I'm not trying to sell anything, although I've spent a lot of money on products based on pain reduction, and products related to treating these cluster headaches. The shock for me was the speed the diet change worked. Normally, regardless of what I ate, I would get clusters between 7pm-10pm in the evening, especially during the summer, and they would last for an average of 3 hours.
My exact new diet:
I started off with a morning breakfast smoothie:
1 banana, two cups of mixed salad greens, 5 strawberries, 3 celery stalks, chia seeds, 2 cups of water. Blend and drink.
I also started taking a couple supplements in the morning: Non-flush Niacin, Vitamin C, Multi-vitamin, B-12.
Lunch is salad: Bowl of salad greens, 1 whole tomato, handful of red onions, 1 avocado, vegan salad dressing (Only way to get dressing without processed chemicals.) I add about a cup of white rice and black beans on the side.
Dinner is where I play around with different ingredients, but I specifically stay away from dairy, meat, and processed foods.
Creamy Potato soup: Potatoes, celery, onions, garlic, and carrots. In a pot sauté until celery is clear. Add vegetable broth until covered. Boil for 20-30 minutes. Take half of the soup out of the pot and blend. Add blended portion back to soup. Delicious!
I drink green caffeinated tea, sometimes black coffee, and water only. No more sodas or carbonated beverages.
It's been wonderful to come home and not have to worry about the pain creeping in, so happy! I hope my posts can help others with their pain.
