I am not taking any pain meds yet. They told me that the cisplatin could cause it. I have struggled with it all my life but normally colace tablets work. Not this time, nothing seemed to work. I am okay now. I am just going to make sure I am drinking a ton of water which I do not seem to be able to get enough in me. My lips are always dry and I am coughing all the time. UGH. It will be over in a few short weeks.
