He didn't have any odd behaviors start, it really needed me making the connections--I'm nursing -> I'm feeling quite a bit better, and quickly -> uh, could I be causing a problem -> increase his vitC (he'd been steady at 3 grams per day for a few months at that point) and increase and increase, and whoops, he's up to 12 or 15 grams, around there. This whole process of me starting the lemon juice, then stopping, then tapering his vitC up to see how high it was now took maybe 3 weeks. But the insidious thing is, I _didn't_ see behavior changes, so even a kid who's fairly marginal could still get an increase in ingested toxins without showing behavioral/mood type issues.
And honestly, the bowel tolerance part isn't really a problem. I've been dosing the kids 3x/day with vitamin C for more than a year and a half now, and between having a good idea of how much they need and how quickly to go up (just due to experience with them), I don't (usually) overshoot so much that they get really bad diarrhea. It's mostly that loose, more urgent poop that's within an hour or so of their vitC. Like all of us, I spend too much time thinking about my kids' poop.
