If I remember correctly, you are on the TFL program in which case I would sub in the scuba diving days as off day work outs. If the three main days is really too much and cannot be made easier with all the thai chicken and rice, I would lighten the weights on the main movement and on the heavier assistance exercises.
If you are feeling really drained just do the assistance work for the three main days around the scuba schedule and start things back up next week.
