Check yours and ask if you have a relaxed neck position.

BTW if you tend to yawn a lot on the boat after a dive, then your breathing has been incorrect.

I don't quite get this. In order to have good trim and therefore be able to move efficiently in the water you have to hold your head back to be able to see where you are going.

The alternative is to adopt the attitude of a sea horse and we all know how inefficient that is for a diver.

I hold the position you describe as wrong but do not suffer from neck strain nor headaches so I cannot see how it's related. The causes of the headaches and fatigue are much more likely to be CO2 retention and inefficent offgassing procedures as already advised.
