I just signed up

Good morning. I just signed up and wanted to say hello.  I lost 20 pounds on WW.  I noticed this site is similar and free, so I am going to give calorie counting a try!  any suggestions for keeping track when a computer isn't near (like at work). Do you carry  a list of your favorite foods and their calorie content?  A small journal to track?  I want to be successful here.  Thanks
