I am returning to the UK from Australia in July 2022 for up to 3 months. As a Medtronic pump and CGM user, can anyone tell me how I can acquire MiniMed Reservoirs and SureT Infusion Sets which I currently buy from my local chemist? Are these available to buy over the counter or will I need to get them on prescription? My suitcase is already going to be packed with enough Guardian 3 Sensors to last me 3 months. Thank you.
