Hi Larry,
They put in a 25mm device.
I thought I might fail as I am still getting headaches, not full blown migraine but similar. A nagging headache behind the eyes.
So lets see what 6 months brings. Hopefully it will be clear, but there is always the chance there could be another hole

Will worry about that on the 2nd Aug.
Capernwray is booked for Sunday.
I look forward to receiving the book Gloc.
Cheers,
Ali
