Progression Regression

Hi there.  It's me again.  You remember me right?  I'm the one that was blogging so much about my weight loss.  I know I've been kinda quiet lately and well....I can explain that.
I have been lacking in the blog department because I've been lacking in the weight loss department as well.  And to be completely honest, I'm embarrassed even though I have no reason to be. 
I am down 70+ pounds from when my weight loss adventure began.  That is amazing.  I am still slightly over 100 pounds away from my goal though and I hate when I plateau like I am now.  I have plateaued in the past but I knew the reasons then.  I was just plain lazy.  I reached and sat at 50 lounds lost until joining a gym last May.  Since then I've lost the other 20 pounds.  In the last month though I have barely lost anything.  I go to the gym when I can.  Granted I slowed down when I had other things tying me down but this past week, I went 6 out of 7 days.  I get 30 minutes cardio and then move to the equipment.  Due to my lap band, I CAN NOT over eat.  I drink a protein shake for breakfast and lunch.  Dinner varies but most often it consists of Soup or Salad.  My weakness lately has been salty snacks.   Not chocolate or sweets as most dieters crave.  I have had major cravings for salt. With all that said.....did I lose anything this week?  No.  I actually gained weight.  Ok, so its only a pound, but I am pulling my hair out over it because I can't figure out what I'm doing that could be so backwards.  I have been given completely sensible advice from many but I still feel discouraged with myself.  I know that from working out I am gaining muscle which weighs more than fat.  I KNOW that I am always getting compliments from all kinds of people for the changes they see in me.  And I know that I have gone from a size 26 to a now loose fitting size 20. 
Knowing all of this should be pushing the discouragement away but what can I say?  I'm greedy.  I want more, or should I say less.  But fear not,  even as discouraged and disappointed as I feel with my progress, I have not and WILL NOT stop moving forward.  I just have to hope that my efforts will not go unrewarded and my body will catch up in reality to what I see myself being.
