Im a planner too. I found that no matter how much I planned nothing could have prepared me for the hardest weeks of my life. Relax and enjoy your time together. Make memories, go out to eat, etc. Your husband needs to eat all his favorite foods now. His sense of taste will change and food will probably taste like cardboard plus he could have swallowing issues that prevent him from eating properly. Have your hubby make a list of all his favorite foods and then you can make certain he gets them all at least once before treatment begins. If he is on the thin side (being military he probably is), he needs to bulk up before treatment starts.

Dont waste time worrying "what if", it will never ever change a darn thing. Make the here and now your main focus, everything else will happen no matter what you plan. Being a planner myself, I know its not easy to not make plans. Maybe planning to make all your husbands favorite dinners will help fill your time. Hope you like to cook
