I put this in as a new post since my reply to your old post would be on the next page by the time you read it, likely.
I take a vitamin/mineral combo (vitamins in the a.m. and minerals in the p.m.) from BodyWise. They are in the ever-unpopular tablet form, though there is no industrial glue to these and you feel their effects within as little as 24 hours. You can take any mineral form you like, I doubt it has to be this brand of minerals. I am simply a devotee to it because I've been using it on and off for nearly 4 years and always marvel at the results. Tried other supplements but none did for me what this has done. Everyone is different so your mileage may vary, as they say. ;o)
But, the important thing is that within a week of going back on the minerals, I noticed my severe dry mouth problems begin to disappear. I have little trouble now, 6 weeks later. I think it's important to take minerals in the evening (I also take a coral calcium supplement in the evenings) since they have a chance to heal any damage you do to your body during the daytime. I wake up feeling much more stable, physically and emotionally. And, I sleep like a baby.
