There is a fellow, I think in Belgium or Holland, who developed an app for tracking a lot of data related to CH attacks, medications, etc. The name of it is on the tip of my brain, but it's not coming through to me. Trying to find it at the app store, I see there is an app called ClusterUck that might be similar. These folks might have a lot of data. There have also been some major studies of people with CH, most recently one from Larry Schor and others and before that, one by Todd Rozen, that have gathered and processed a whole lot of data; and there is the current one that you can see here: https://clusterbusters.org/forums/topic/13151-cluster-headache-medication-psychedelic-use-survey-2023/.
