I remember those two weeks vividly. I guess its like stopping a train or turning a ship at sea. The effects of the radiation have a certain amount of momentum and don�t start to diminish for a few weeks. I too felt those two weeks where the worst. Painkillers sleep and liquid food; that was my existence.

The good news is that your two weeks are over and you should notice a gradual change. Mind you, its not much at first, but it should get better soon.
