Agree with the rollercoaster analogy. I share your feelings - only mine still cycle within any given day or hour. Ugh - it seems like it is the worst during the day when my mind can wander and i am convinced it is a hopeless cause-then I see him and am determined to stand and DB for however long it takes - sometimes.Tonight it even changed within 1 hour of seeing him - he picked 1 kid up at the house (standing) then i saw him walking at the park and decided that I don't know why I am wasting my time on him - I never really liked him anyway - wow - that was a shocker to me - I thought to myself - now I am re-writing history similar to what they do. And finally at this time of night I am neutral either way. crazy!!!!!!!!!!!
