Claire--
I was banded in July 09. I've lost 72lbs and have had 4 fills. The last fill was in March 2010 and was way too tight, so I got an unfill the first week in April 2010. Things have been going well until about 10 days ago. I'm not sure why, but all of a sudden I can't get anything down including Water. I ended up meeting my surgeon in the ER last nite to get a slight unfill (again). He took out 1/2 of a cc. I waited for over a week because I kept thinking it was going to get better plus I, like you, feared gaining weight with an unfill, but what happened was that I dehydrated myself. The other posts are so true....it doesn't matter how much is in your band as long as you have restriction. I'm on this site all the time, but rarely post; however, this just happened to me last night and thought I should share.
Take care,
Dore
