I want to be a loser

I hate to admit how complacent I have gotten with being healthy.  I know what I need to do which makes it much worse than just being ignorant.  I know how to count calories (or points).  It's a simple equation more output than input.  Add in chaos and the need of convenience and it no longer seems quite as simple.  In addition to the chaos I have a huge weakness for sugar!  Preferably the chocolate variety.  But really any sort of 'sweet' will do.  
My hubby and I came to a so called agreement right after Christmas.  I will give up sweets and he will give up soda (his weakness).  "Give up" is so very harsh.  Neither of us has been perfect with it.  He of course has done much better than I.  Unfortunately for him I am weak and when I have given into my sweet tooth I have tended to bring him a Coke.  Oh only upon typing that out did I realize how horrible I have been.  Did it take anyone else back to Genesis?  Ouch.  The above reason though is why accountability in this area does not work between us.  I know that he could never really stick it to me about what I am eating.  
I know that I need some accountability though.  Honestly it is not enough for me to want to lose weight for myself.  I need the accountability.  That is probably one of the biggest reasons that Weight Watchers worked for me.  I have been praying for some guidance.  I know what I need to do, but wasn't sure where to seek out the accountability.  Do I go back to WW?  Find someone who will keep me honest?  
Well, I may have gotten my answer.  A week ago Saturday I received a postcard in the mail from a local gym.  They are doing a 36 Week Weight Reduction Study.  Honestly, I think it is a way to get people in the gym.  But I'll bite.  I called and waited for a call back Tuesday. Qualified for study over the phone and had a meeting later that afternoon.  
As usual I arrived early.  While I waited in the car my stomach had butterflies.  Yes, over the gym.  I honestly cannot remember the last time I was in a gym.  I think it was roughly 7 years ago and then I at least had my hubby with me.  When I went in the guy wasn't there yet so I had to sit in the middle of everything and just wait.  Ugh!  Stomach was really upset now.  I so wanted to run.  What was I getting myself into?  Gym.  Accountability.  Schedule.  Consistency.  This is a good thing though, right?
This time it is no gimmick.  No special diet pill.  No counting points (nothing against points).  This time I am going back to a gym and eating like I know I should.  Hard work.  Dedication.  That's what they say on Biggest Loser and it seems to be working for most of them.  I have a long way to go before I can get this body of mine healthy again.  It will take loads of dedication and perseverance.  Tons of hard work.  I know that once we set into the new routine and I start to see results it will be so worth it.  I know this is a good thing.  I have not taken out regular time to do this in the last 5 years or so because I was "too" busy and there were other things (and people) that were more important.  But how busy am I going to be when I can't do anything and I watch my life pass by and not be able to participate in it with my kids and hubby.  Or worse yet, how busy will I be dead.
