Paul hopes you will be able to find this one quickly, as the waypoints are very close together.
Waypoint 1 is how he started trying to get rid of the headache. It didn't work, so he moved on to search for something better.
He left a message at his first attempt to guide you to his solution. Go there to see what finally did the trick.
Now he's pain free and wants to share the pleasure with you.
Beware the nettles lest you have to relieve your own pain.
