hitting a rough spot

I have never posted to this board.  My name is Hope and I was banded Oct 20, 2006 in KC.  I have lost 60 of the orginal 334 ilbs that I started with.  My question is, has any one else out plateu and how did you get started again.  I have not lost anything in about 2 months.  I exercise for 30 minutes to 1 hour 6 days per week.  I have 7.5 cc in a 10 cc band.  I am not feeling the restriction that I once did.  I had been at 7.0 CC a couple months ago and they had to remove some of the fill because I was too tight.  Since that removal I have not been able to lose any  more weight and I feel like I am as hungry as I was pre surgery.  I have talked to the nurse at the clinic and she said that I just have to hang in there.  I am really fustrated with it all.  Any one else there have had this problem and what did you do to get the weight loss started again. Thanks, Hope
