Thanks for all the great advice, guys.

I recently noticed -- I'd been unknowingly taking dextrose sweetener and spiking my blood sugar. I usually buy a store brand stevia in plastic tubs, but two weeks ago, the tubs were sold out and I bought a box stevia packets of the same brand. But yesterday, I read the label and was horrified to see: while the tubs of stevia used stevia and erythritol, the packets use stevia and dextrose -- which may be why I've been hovering around 190 for two weeks and been feeling cravings still. I threw out all the dextrose and restocked on the erythritol stevia.
