Bitter taste in mouth (Page 6)

I get a nasty taste at the back of my throat that makes my throat really itchy/scratchy my month waters then more often than not I'm sick. I'v had it 4 the last few months now on and off. I would really appreciate any help right now.

I also have a bitter taste in my mouth for the last several days, but not eating any pine nuts! I have it all the time and food does not taste good. My taste disturbance is worse in the morning when I drink coffee with cream(dry or liquid) as if my taste is so bitter in general, like a metallic taste. I thought maybe my water softner/filtration as not working and the water I use to make my coffee might be the cause. What else could it be causing my bitter, metallic taste does anyone have an idea?
