I'm sure you will enjoy this board...there are so many positive...helpful...friendly people here.
I also have ....(had) over 100 lbs to lose. I try not to think of it that way tho. I make little goals for myself. Like 10 lbs was my first. Then my d/h bought me a purse. My next 10, I am going for a massage....etc. You get the picture. I find that for me, looking at the BIG picture...I get frustrated. My first big goal is to get below 200 lbs...that will leave me doing the happy dance.
Good luck to you...and you are lucky that your d/h wants to join you in your journey to your new life...
