I like the Bickfords Range of cordials, just havent bought them for a while....on my shopping list! Nurses suggested Biotene and its pleasant enough for me to try it. On tank water and hate town water, so that not an issue but Ive never been a fan of ice cold fluids....throw a bit of ice in room temperature I can cope with but straight from the fridge it sits to get rid of the chill. Strange I know. Tried the vegemite but unfortunately despite the ads we cant live on it...:) Thanks again for suggestions and advice..I will overcome!!!! And best of luck to you all...hugs
