Interesting. I'll have to try this, who knows? In fact I have noticed that my tinnitus can vary, sometimes a lot in intensity. Sometimes it seems almost slight (but always there), sometimes pretty loud. I have not been sure how subjective this all is, it can't be objectively quantified.
I visited a cousin almost a year ago and they used stevia for sweetening. I looked it up and bought
BulkSupplements Pure Stevia Powder (100g) at Amazon. Boy, this stuff goes a long way, you don't have to use much to get sweetening. I haven't been using it for all my sweetening, but a lot. For instance for lemonade it's great. I like it in a lot of things, including coffee. Sweet for sweet, believe it or not, I believe it's cheaper than cane sugar if you get the linked deal! I'm pretty sure it's
way healthier! I add it in powder form to some of my cooking and make a solution with it for other things, including adding to coffee, from a little bottle with a dropper (1 oz. water + 1.5 teaspoons stevia powder).
