Markus,
I had the regular, full dose, dispensed over a period of several hours, after the extra hydration and benedryl had been run into me. Even at the lower, weekly dose, I would imagine that hydration will still be an important issue.
Just a note to say that I believe absolutely that chemo is a very important part of the treatment. I had a large tumor with involved lymph nodes, and am healthy and happy five years later. When I was treated, there was no certainty that chemo was as effective as it is now known to be. Further, there was no option for the weekly treatments you will be receiving, which I think makes a lot of sense. As you may be the first person here to receive that form of chemo, I hope you will post to let us know how this affects you. Changes in treatment are being made all the time, and this may be an important one.
Good luck!
