Dose any one else Feeling like I will never lose weight...

I also am loosing slow for after surgery 4.5 months out and only down 50 lbs ..

i was happy with that weight loss but the dr and the nutritionist was not!!! 

I only want to loose another 40 and I exercise 2 hours a day and still the scale is slow to move ..

but I keep putting one foot in front of the other and hope it gets me to the end one day
