Welcome back Lola. If you have to dust off the elliptical--maybe you don't like it. Have you tried any other exercise class's or programs, something that you like doing? We have found that if people like to do something they usually stick with it. Me--I am a social person, and have to work out with others, otherwise I won't work out. So Jazzercise is my addiction. That hour just flies by.
Also if you have a smart phone--android or I-Phone several of us bought the Fit Bit--showing you how many calorie's were burning--how far we walked that day--and you can add free apps for calories/carbs you eating during the day that syncs with the Fit Bit--to tell you exactly what you're eating--what you need to eat to get to your goal weight etc.
I have found that the calorie/carb apps on these phones really help me to watch what I am putting in my mouth. Very helpful to me anyway.
Good Luck--you can do it--just make a plan and stick with it, no matter how long it takes.
