Hi Mandy, I am in the UK too. Ensure is avaialbe here to but I was prescribed Fortisip which is very similar (you will find them on Amazon but you should be able to get them on prescription or from the hospital). I still use a bicarbonate of soda solution regularly as a mouthwash and when my mouth was very sore I was prescribed Diflam/Benzydamine (Oral rinse - locally-acting nonsteroidal anti-inflammatory drug with local anaesthetic and analgesic properties) and also Antacid and Oxetacaine suspension (made up at the hospital but like Mucaine)which between them have a similar result I think to Magic mouthwash. This forum will give you a lot more info than I could squeeze out of my doctors so make good use of it, there is loads of helpful info here. Good luck with your treatment. Sally
