Plateau

So I think I've hit my first plateau, for some reason I didn't think I would hit it at 186, being that I have so much more weight to lose. I figured somewhere around 150 or so that would happen. So what do I do now, my time is extremely limited, Im in school full time, I'm a single mother to an 8 month old, and work full time. Just all around tired. I do work out Mon - Fri for 45-60 minutes. Since I started working out 8 weeks ago, I started on the elliptical and I'm afraid that is the problem, becuase that is the majority of my workout. I thank the elliptical for helping me lose 17 lbs, but I think I need to befriend the stairmaster (which I super afraid of) and perhaps the treadmill. I'm also going to start planning my meals better for the week ahead. Yesterday I bought Jillian Michaels 30 day shred and I was super excited to start my first workout, but I lost the remote to my dvd, so I will be going out to buy a universal remote today. I was so mad, couldn't even toggle to the workout! lol! But at least I did burn 500 calories earlier at the gym that day. So spark friends, any suggestions on how to overcome this plateau, yes I know its a lifestyle change, and that I shouldn't solely rely on the scale. I'm working on doing better with that. I really need to focus some more attention on strength training as well as the cardio...hmm not enough hours in the day. Well wish me luck with the 30 day shred today!
