Antiemetics in the UK

[E.T]

Hi.

I'm in the UK and will go to my GP soon to ask for antiemetics, specifically meto, as part of my SN protocol.

I just wanted to know if anyone has any experience with this, or could share the ideal thing to say to get them to prescribe them for you?

I'm planning on telling them I'm dealing with migraines and nausea. It's technically not even untrue. I can't eat because of the sickness.

Will this suffice? Or is it possible it'll take several appointments and an investigation into the cause of my nausea for them to prescribe AEs?

Thanks.
