you seem to be getting 100 mg/m2. (strange measurement, for some amusement ask a physician how the get to m2)
It seems to be more common to get weekly doses (around 30 mg/m2) of cisplatin these days. These seem to be better tolerated that the 3 mega doses which often could not all be given anyway. You might want to inquire if that is an option for you as well.

Also.... cisplatin can cause hearing problem stay on top of that.
