Besides eating as much as possible, and lots of paper and pens, if possible, take a small recorder with you and tape what is said to you about everything. It's easy to forget as when they talk, your mind is travling around wondering about this crappy disease. Then when you are home away from the prssure of treatments, you can replay the tape and even then maybe write some of the info on paper. You will be drinking a lot of water too, which we all do, so stock upon a few cases unless your tap water is good ithout some of the chlorine and others tastes in it.
