Stuck in a rut

I've been stuck in a rut lately. I've been trying to lose weight for about 2 years now, sometimes with more success than others. Right now, I am stuck in a rut. I know what I need to do to be healthy, but its a matter of actually doing it. That's the problem it seems. I can't get beyond adding it to my to do list and actually doing it.
For one thing, I love my soda, and I've never drank diet. Regular coke or dr. pepper thank you very much. Orange soda is a close second. I was doing really well with drinking water or crystal light, and then one day I rebelled. That led to my downfall yet again. My other issue is I wind up STARVING about 10 am. As a result, I start eating everything in sight. What I need to do (here again, I know what healthy choices I need to make, its making them) is have some fruit or yogurt. That's all-something simple but once again I choose junk. And my waistline shows it.
Can I let you in on a little secret? I love to exercise. Really I do. I love how I feel when I go on the treadmill. I love how I feel when I bang out some weights. And I especially love how I feel when I do yoga. But I torture myself and not workout. I would rather do 30 minutes on the treadmill than anything else like down a bag of chips. However, I have not been consistent for a very long time. All it takes is me getting up in the morning, putting on sweats and going downstairs on the treadmill. Nothing more simple, yet I do not do this. We have a home gym-its not like I have to go somewhere and do things. All I have to do is go downstairs in my own house.
Part of the issue is I feel like if I do this then something else in my family will miss out. Stupid thoughts I know, but its what goes through my head!
But here I go again. I bought some fruits to eat as snacks at work-I love grapes and grapefruit. I planned healthy meals for my family. And most of all I will get up off my duff and do something.
Maybe even now!
