I also am a cancer survivor and during treatment I was so much more aware of what I was eating. At times I drift back to old habits, but being aware of it and know what needs to change is first step. Making the change is harder.

I have same problem with late night snacking. One thing I find helpful is doing something with your hands while watching TV. I crochet, it is hard to munch on food if both hands are busy, also do not want food on my yarn. I make dish rags, nothing fancy and do not need to be accurate, just something to do with hands. Other ideas are coloring, reading instead of TV, anything that keeps your mind and hands busy.

Do you have any hobbies that you can do at night instead of snaking?
