I think if you don't see some green numbers by morning, I'd take the dose back up to f1u. I am sorry I missed your condo yesterday (work day for me). Remember when you are stalling, don't feed him. As luck would have it, he was headed up into a bounce but you wouldn't have known if the 219 was end of cycle or a food spike. If it had been a food spike, he could have come back down on you.
I get why you stalled yesterday and you did the safe thing which is smart. But, let's say you were going to be there and not have to go to bed. It would have been very safe to shoot the 119 because he had already hit his nadir the cycle before, came up, and then got a second dip with the 119.
Have a great evening.
