After was distracted from any computer tracking for 2 days , I realized I 'd better get myself a pocket diary so in a snap I can jot a note of what I ate or activity I did. It's so difficult to go back and try to remember what I ate or activity I did. Much easier this way! I can go back and enter it into tracking and not feel anxious that I may forget or let it go to the wayside and get off track . And it's always with me in a pinch !
