hello and welcome, I used to live in the Fremantle area also (Willagee to be exact) till i moved to Canberra in January!!
I know what you mean about the trying various things and not getting the desired result, have been there also and started "doing it my own way" nearly 2 weeks ago and i am finding it sooooooooo much easier than any of the programs i did, i think because i am still eating food i like and i'm not getting that sense of failure if i eat something i'm "not allowed" to eat
anyway, i look forward to hearing of your progress, i find this forum and these people very supportive, whether you're doing good or not so good!!!
