Suggest Treatment For Throat Tightness And Hyper Salivation

I am having difficulty with throat tightness, excessive saliva production. This becomes particularly annoying when I am talking. I am not a big talker but am a psychologist so need to be able to think about what my patients are saying and not on keeping my spit in my mouth! Any thoughts? I do need to lose weight which I am working on this year and think this will help some.
