There are a few of us that have never had a fill.  Some on this forum lost all of their weight without ever getting a fill.  The most awesome I remember is a woman that has reached goal (actually I think under goal, 147 lbs) without a fill.  I am nearly at goal and as such beleive I will be able to do it without a fill as well.  Right now I am working on toning and think that it will get me over the last few lbs/inches to my goal.  All that said, I am so sorry you are having so many issues.  Hang in there, I have faith that things will turn around for you as you travel on this adventure.  If there is anything I can do to help, whether it be a venting spot or what ever you need, know that I would do that for you.  You can send me an email and I will give you my #
