I have a problem with dry mouth?

I have developed dry mouth a side affect of the anti depressants I take. I have had it for seven months and it seems to be getting worse. What I need to know is has anyone ever experienced this and did the dry mouth go away on its own or did it go away once the medication was stopped.
or does it stay with you even when you have stopped the medication. has anyone switched medication to stop the dry mouth and was it successful if so what switch did you make.

There is a product that is supposed to help dry mouth - I have no idea if or how well it works - it is made by the Sensodyne toothpaste people - Glaxo-Smith-Klein.

Oasis Moisturizing Mouthwash for Dry Mouth

I think they make a mouth spray too.
