Just peeked at your SS. Do you think those green nadirs a couple weeks ago were from the scheduled feedings, i.e. he wasn't eating anything around nadir time? I think you said you've abandoned scheduled feeding right (or am I thinking of someone else? :dizcat , so I'm guessing the curve would look different with more eating mid-cycle. I'd be a little worried the dose might be a hair too high if that's not the explanation. It would be interesting to see where he is landing mid-cycle these days. Some of those PSs are pretty darn good!!!
