Woke up at 5 a.m. with cluster on wrong side, maybe at a level 5. Feels weird though, like it's a migraine in the cluster spot, but not really, it's definitely a cluster. Maybe I'm just not used to having them on the left side.

Katy says: He dozed off in the bathtub around 5:45, woke up suddenly 10 minutes later and said very clearly "HELP." Keeps falling asleep in short bursts and waking up suddenly.

6 a.m.: May be starting to break.

Moderate headaches, switching sides the rest of the day.
