Resolved Question: Serious people only please: I want input on my weight-loss plan... and suggestions...?

I'm 22 years old and am very much overweight. Probably about 50lbs because I've had surgery on my leg so I was confined to a wheelchair for approximately 6 months and the medication made me gain the weight :(

My plan:
I have an eliptical and plan to use it for 30 minutes in the morning before work and for 30 minutes in the evening sometime. Each time it's approximately 300-400 calories burned.
Obvisously, I need a good diet as well. I'm drinking Wu-long Tea 2x a day (it's like a detoxifier tea). I also plan on taking Alli so my fat intake has to be monitored. Low-fat and low-calorie diet.
I am lazy and lack motivation to do this and probably keep up with it.
Also, one of my biggest problems is snacking. Although I try to keep unhealthy snacks out of the house, I snack a lot! I think I have some sort of oral fixation because if im not snacking, I'm chewing on my fingers (biting the skin on around the nails).

Please help

Are there anyone who's done a similar weight-lost plan and have acheives their goals?
Are there any suggestions that can help me stay motivated?
Any suggestions on my snacking problem?
