i am an episodic cluster sufferer. My cycle is 2yrs of remission with episodes that were 6weeks long until I started accupuncture and stopped taking the heavy duty pharmaceuticals, now they go for 3weeks with attacks at 3am, 5am, 8am, 10am & noon every day for 3long weeks but I do get a nights break after my accupuncture session every third day. it is a living hell and wouldn't wish it on my worst enemy
