I'm happy to hear that has worked for you so far and I hope it continues. I have gone a similar clean eating nutrition route. Also, in September 2018 I even went all-in on intermittent fasting (no eating for 12-16 hours, then I eat a normal amount of calories in remaining hours). I lost 32 pounds in 14 months. We even experimented by reintroducing some foods back into my diet short term to see if they would trigger CH. Anything to isolate the beast.
Bottom line... My weight went down, my blood panel numbers (including micronutrients) improved dramatically across the board, and my energy went up. Unfortunately, I also went from episodic to chronic CH during that time. I feel better but can do less because of my debilitating CH condition. I had a seven-day stretch in early November when I had only four attacks. I thought for sure I was headed back into remission. That was followed by seven days with 35 attacks. There were no changes in nutrition, sleep or anything except some youthful optimism at the beginning of the second week. At least for me, CH is definitively not nutrition-related.
