WFC,

I think you are doing better than normal...the first two weeks after RT are generally tougher than the last two weeks of treatment. Keep yourself awake enough to get your calories and fluids in and sleep the rest of the time away. If you are like the majority here, between week 2 and 3 post treatment you will start to feel signs of improvement. You might backslide here and there, but overall you'll start to head in the right direction.
