Does anyone have a really dry mouth? If so what do you use.

I’ve just started some new medication and it’s making my mouth really dry and my tongue is sore and sensitive as a result. I wake up in the night and my mouth is completely dry. There seem a few different products for dry mouth, can anyone recommend a particular one?

My Mum has a dry mouth and her Dentist gives her Salivex. She gets it on prescription but I'm pretty sure you can just buy it.
