I've always used this forum as a reference point so it was high time I joined!
I'm 21, 5"6, a yoyo dieter, and have lost 20 kg twice in my life only to put it back on.
My first time I lost the weight I had joined Jenny Craig and Curves gym. I went from 94kg to about 75kg in about 9 months the good old fashioned way, but I don't think I was in the right mindset to maintain my weight. I hated Curves and I think that was my downfall to stop progress and put it all back on, along with TEE exams.
My second time I lost the weight, I was prescribed Reductil then Duromine from my doctor and the weight dropped off. I exercised along with this but I think I took it as an easy fix and cheated heavily and the weight still dropped. I was on Reductil for two months until it stopped working, and Duromine for three. I reached the weight where I've been most happiest in my life - 70kg (26kg lost) - and from there I maintained for over two years. However, last year was a hard one. What with a boyfriend who can eat a truckload and not gain any weight, family issues, and contentment (I guess), I piled it back on.
I am actually so disgusted that I let it pile back on when I was so happy! I get to the point where once I gain two kilos or so I (for some reason) lose some hope and just sit there and watch.
But not this time! I have joined Jetts gym, have at least four workout buddies, and really want to start swimming again at least once a week. My doctor has prescribed Duromine for me again and even if I only remain on them for a month I know this will be a good kickstart for me.
I have 30kg to lose, and it will happen!

Hope to meet a few great people in this forum along the way.
Britta.
