Woke with nagging pain on the right side and wondered if it was just a regular old garden variety headache which I assume I still get but don't often notice.

around 11:45 I was feeling really tired so I decided to read in bed and fell asleep for a few minutes. by the time I woke up I was feeling the familiar ramp up of a classic cluster attack.

It got up to around a 5 or so and lasted for about one and a half hours from start till breaking and quickly stepping down as the classic ones do. I can still feel it a bit but its mostly gone for now.
