Thanks everyone for your support.
The clusters have seemed to ease off. I've only had one or two minor attacks since I started this thread. Very weird.
My migraines are easing a bit too (knocks on wood). My daughter is down for a visit this week, so I've taken some time off work. That might be helping things. Hoping to bust soon, once she goes home and I have a week clear of triptans. Which may now be possible. Hoping to get 3-4 busts done in fairly quick succession.
Hope everyone is enjoying the summer.
