I like the way my doc does it. He doesn't do it under fluoro (doesn't like that unless essential because of the radiation) but after a fill, he gives me a drink of water. then he gives me a smooth, thick yoghourt. If i can eat half the pot (large one) and feel comfortably full, we know i am just right. Less, i am too tight, more I am too loose. So then he then adjusts it there and then.
This has worked perfectly for me with every fill. I have always left his office with excellent restriction. Just once I was not sure and erred on the side of caution and it was not quite enough.
On a financial note, if the fill is not right and you go back a few days later, surely he shouldn't make you pay again? The one time i had to go back, I went a week later and he counted it as the same fill and justt charged me the once.
