My husband, Dana also used a dry erase board for quite a while. We also used our own sign lanugage, but the first thing he wrote on the dry erase board was, "you really suck at charades"! I agree with everyone who advised you to write down questions for docs and take notes when they answer. It's good to be able to rely on your notes when things get emotional. I also started a word document on the computer with Dana's ever changing medicines. Every new doc got a current printed list. We kept a packed tote with magazines, a blanket, and med list for chemo or unexpected hospital visits.
