MG's first rule of clusters: No two cluster sufferers are the same, and just as soon as you figure yours out, it changes.
Really glad you found a system that works for you. A lot of people report that physical exercise helps with clusters, and a good diet low in processed foods and sugars is always a good idea.
I'm sure you'll find people who find this method works, and just as many that don't. As an example, for most cluster headaches, alcohol is a massive trigger. But not for me. In fact, I can use it to abort a migraine if I have to. We are all different.
