Can anyone give me some feedback on Salivart? I sometimes use Oral Balance at work but, if the Salivart works as good or better, it would sure be easier coating my tongue with a spray than a gel. It's embarrassing to be training somebody and have to stop every 5 minutes for a sip of water or to put the gel on my tongue. Also, how long does the Biotene mouth wash last?

Thanks for your input and advice.
