I was able to sip for about 10 hours after my fill before I swelled up so bad. This happend the last time too. After I had to have fluid removed 6 weeks ago, I had almost no restriction. I am not sure how much fluid is in my band, but I had my surgery last year Feb. 6. And, I have been having adjustments (small ones) every 6 to 8 weeks. But, now I need to get the band where it needs to be, but I have a swelling response.
