Various stuff, including oddities, that might help someone (so why not try to tell or show it?) :
For some reason (absentmindedsidetrackableness?), it's my second pint of water of the day that gets later and later, causing me, then, to get to the end of the day either without enough water or drinking so late that I awaken through the night unnecessarily. Just recognizing this helps. But I try to notice either a time of day or beginning the preparation of lunch to get in the next pint, and that helps. (as Ramblin' notes, important for avoiding digestive frustration)
Here is what I'm talking about with circling habit charts : I use this one, which has space for 31 days, date plus 12 daily spaces per wedge for check marks in color (or just any pencil, for that matter), and this one has a bit of fun design. It's an instant glance to find out if I haven't had a beans serving or other planned serving yet today, especially if I do use colors. It requires getting it printed, of course, so I'm lucky that HRH has a copier, but if it went on the fritz, I could still get a dozen at a time at a copy shop.
Here is what I'm talking about with planner area to right used for food log. Mine is a very plain, cheap planner with spiral like any spiral notebook. If I continue with planner next year, there are so many formats to choose. I'm not sold on this - it's just so obvious a use : 3 spaces for general 3 meals, written briefly so that there's no wondering exactly what I ate. It's not just a checkmark for a grain, for instance, but written out "brown rice" or whatever. Also, the compactness of keeping food log with the rest of the planner notes in one little book is a plus.
