Still feel fat

It has been three years since I had RNY surgery with DR. Nohr in Medicine Hat.  I would have done it sooner if I could.  After losing 100lbs I still have the extra skin hanging around my middle which looks like a big fat belly wich i cannot get rid of no matter what.  There is no way I can lose any more weight I have tried going back to 3 shakes a day and exercising and even that didnt work after a full month of trying.  I think because of where I work we are not able to eat on time or drink water when we are working, that may have something to do with it.  I see that everyone is doing well and wish I could manage to make it out to one of the meet and greets. 

have you looked into getting a tummy tuck or a panni done?  I'm 100 down and this last 20 is killer....
