Sorry to take all day to get back - very ill husband.
I asked the GP, he hadn't heard of it (which I expected so I'd taken the freephone number off their website) explained that he had to ring them to get an information pack sent to him and I said something like 'I think they do it that way to stop the anorexics from buying it' He said he'd never prescribed it before and I said 'you don't actually prescribe it because I pay for it, you just say I'm fat enough to have it, and it's better on your budget' All said with a silly grin, but he agreed. He was about a month getting it sorted though, but he was impressed with the stuff they sent him. I'd started on CD - sick of waiting - so I'd already lost a stone by the time I went to get my packs. He's well impressed now. I don't know if the GP is any cheaper than the chemist though. I pay £32 for a week. Will I pay more if/when I add bars? You do on CD, and the drinks mixer is £7 a pot.
