Very glad to hear this, Jeff. Do you mind saying the name of the supplier?
I'm going to assume that you know that melatonin at night helps many with the nighttime attacks (melatonin levels are quite low in people with CH). Starting at maybe 9mg.
Hopefully, you'll get your aborts down considerably below 15 minutes over time. Some research shows that just in general aborts tend to be slower in the beginning. You'll get a breathing rhythm that works best for you. Recommended is big inhale, hold a couple of seconds, big exhale. It has been written that for some reason looking down toward your feet can speed an abort. And then there's equipment: the "ClusterO2 Kit" mask makes a nice improvement for many, and a higher-lpm regulator will also help if it allows you to use the most effective breathing technique without waiting for the bag to refill. If you're up for it, strong coffee or an energy shot as you start the O2 almost always speeds the abort.
