Abiut 5 years ago , I weighed 350 pounds (I'm 5'9), I got about 150 off in the fcourse of a year. Granted , I had only to deal with Junk food addiction(and still do every day)
I think it is hard with a "get it now" society to make changes like you're trying to make. After all, the Gal taking Metabazap on tv lost 200 pounds in 10 seconds, so why can't you?
One of my favorites quotes is By Chairman Mao(sorry for the politics) "A Journeyof Thousand Miles begins with a single step". Just make sure yor'e making the right steps, and before you know it, you'll be at journey's end
