Looks like the reduction wasn't holding, although you gave Lucian plenty of time to try it out. You did exactly the right thing, taking him back up to the last good dose.
He'll probably be a bit wonky for a few days. Hope he settles into the dose again soon.
I know what you mean I swear Autumn doesn't have an ideal dose, she has an ideal cycle of doses. I keep hoping she will pick one she likes and stick with it.
