Hot Chick in a fat Chick's Body

Everyday is a challenge, some more than others.  I've been at this for 3 weeks and every day it gets harder rather than easier.  I decided to finally do this because I want to set a good example for my kids and I don't want them to be stuck with just their dad after I die of a heart attack...plus I don't really like the idea of the medical examiner seeing my naked body, even if I am dead.  For years I have had a coke addiction, not the white stuff, the delicious bubbly black stuff....excuse me while I wipe the drool from my chin and now I have been coke free for 3 weeks.  Not to mention grease free, I love grease, even just the smell that exudes from fast food restaurants makes me excited.  Week 1, I lost 9lbs...AWESOME!!  My husband(who by the way eats whatever he wants without gaining a pound) was sure there was something wrong with the scale...supportive right?  Week 2 I lost 3 lbs, which is apparently average, not gonna lie, was dissapointed, now as the end of week 3 approaches, I have been stuck at the same weight all week.  Yes, I weigh myself every day..a mistake most people have warned me about but I love seeing how fat Ive gotten over the years on a daily basis.  Actually I find it keeps me on track, if I see Ive gained half a pound, it gets my cellulite filled arse moving.  Every minute of everyday I want the bad good stuff and the fact that its not happening as quickly as Id like is frustrating the heck out of me..  Can someone please explain why gaining weight is so easy and losing it is so darn hard?!  Even as I sit here typing I want a greasy piece of pizza and a large cold glass of coke...guess that means I should go for a walk....
