Hello. I have had clusters for about 20 years. I always felt lucky that they always showed up 2 years apart. Just got through my last cycle which lasted 4 months. This round was particularly brutal. I always had two questions about others with CH. 1. What do people do for a living. I’ve been in corporate world but finding it difficult to continue. 2. Where do CH sufferers live. I always had a feeling climate played a role. Would consistent hot or cold weather help. I live where there are 4 distinct seasons. .
