At the moment I can't see why I wouldn't be able to continue to afford it for life. That might not be the same for everyone, of course. In any event, the likelihood is that the cost will come down over the next few years and also that they will be more widely available on the NHS. They're working on producing a pill rather than an injection which will reduce costs significantly in itself.
I do think maybe the "outsiders" on these threads need to accept that most people who've been obese for most of their adult lives are not going to stop being obese without medical intervention.
It doesn't matter whether that's a moral failing, as they seem to think, or a scientific inevitability, as all of the recent evidence on obesity and metabolism conclusively proves. Obese people may get thin temporarily but they do not, except in a tiny minority of cases, stay thin, no matter how hard they try. Fact.
So these concerned bystanders need to decide for themselves whether we're more expensive and annoying when we're healthy, in work and paying privately for a maintenance dose of Mounjaro, or whether we're more expensive when we're progressively less healthy and less mobile, unable to work for as long or as much (or at all), and highly likely to be in need of some sort of long-term medication and surgery from the NHS anyway 🤷
