Certainly the headaches are typical of CO2 retention but the absolutely shagged out bit could be more to do with how you dive and more specifically how you do your ascents.

Whilst a certain amount of fatigue is to be expected from exertion, especially if one does not normally do much exercise, the type of tiredness at the end of a diving day is normally caused by nitrogen bubbles at a very mild DCS level.

This can be prevented to a large degree by using Nitrox, ensuring slow ascents to the safety stop and then ascending *really* slowly from the safety stop at about 1m per minute.

Try that and see whether it helps.
