I would see how the new meds go JS, it could be that what he is on hasn't reacted well to the first ones. My neighbour said there is a new place in the UK that does the radioactive therapy and they do only have to stay in a couple of weeks, but then they are housebound for a couple more weeks - I wouldnt consider it for Sam, it is either meds or the op for him, everytime you sit down he is on your knee, so even 2 weeks would be awful for him.
