Sorry not to have an answer for you, Twinkle Toes, but I did want to post a quick update since someone asked me to do so earlier after we'd be trying these alternative approaches longer. I fear that we are going to jinx ourselves here, but dd does seem to be continuing to do better on the O-3s and with gum chewing and caffeine than not. Her math letter grade on the soon to be out report card should be a letter grade higher than the last quarter. She got A-s on the last two tests for that class as well. We'll see how it continues to go... Wish me well that I haven't jinxed the kid!
