Benadry makes my difficult child (and me) speed like nobody's business. Just an FYI: It doesn't relax everyone~like all medications, it effects people in different ways.
I see no harm in trying the benadry at least once just to see. Like you, it took me a long time (3 years) to finally give in to the medication suggestion for my difficult child way back when she was 10. She is now medication free.
