@Albertslittletie I went to the GP. It says on the NHS national site that it is available. In practise, it isn't.
To access tier three support which is where this is, you need to actively engage with tier two support - 12 weeks of exercise and dieting and they may consider you from there.
GP said they'd like me to be seen this year to start the process. And then followed up with a text message to say that our area is not prescribing injections or tablets. It's just the support, even within level three.
I think it's good to be on their radar though in case anything changes. I asked for help in January and haven't heard anything since.
All the best with making decisions around this. It's a big financial and personal commitment but it's working for me.
