Well, it's now August and I am down to 72 kilos. I feel so much better: my feet and knees have stopped hurting and I've just started a weightlifting program at the gym to strengthen up. It's taken a while to get to the 'green zone' but I'm there now and finding I usually consume around 1000 calories a day (healthy ones mainly, apart from the occasional chocolate). I have also stopped drinking alcohol. This is one of the things I've noticed with the band - my addictive drivers (food, alcohol, coffee) are all much reduced. As I've previously had breast cancer, which is my primary motivator for losing weight, stopping drinking can only help (it's another risk factor).
I want to get down to business and lose this last 7-8 kilos, so I'm starting to record my food intake again. The fact that I've lost so much weight already, without really trying, highlights how effective the band is. The only side-effect I've had is gas - because it's harder to burp, I find that by the end of the day I can have quite a bit of wind buildup, which can cause pain in my shoulder. I'm going to start having peppermint tea to see if that helps. It's well worth it though, for the payoff.
