Dh gets bad headaches and migraines, especially on days off after busy weeks, or after a lie-in. Apparently the following don't work for him:
Fresh air
Gentle exercise
Sitting reading a book or listening to music
Having a lie-down
A hot shower
Any suggestion of doing any of the above is met with a snap.
But computer games distract him at least. And no sitting rigidly in front of the screen doesn't make it worse or prolong it. Of course.
We're off in two hours for an overnight stay and a fun day out and he's sat in front of the computer with a bad headache.
