Thanks for the replies!
I think the dehydration thing makes sense.... I work 13 hour shifts, though, so I think it's very important for me to remain hydrated. I am not sure what Motrin is? The next time I can see my nurse is 7th September so I guess I will see if any natural slackening occurs in that time.
I was badly overfilled for more than a year which was hell, so was completely unrolled I'm order to re-learn the sensations attached to my band. We have been slowly advancing my fills, working me towards restriction...I wonder if this time, we just overshot the target.
