Well, I do keep trying

Not sure if I've tried the Stevia, but know I haven't tried the agave yet.
I can't smell. I lost my sense of taste and smell due to the injury.

That's why the two things of taste that I can reconstruct are important to me. I have a great visualization/imagination ability...and can sit and dream about how did something (use to) taste??? and recreate it... but it isn't always possible.
So for eating I have hot/cold, texture, colors... and sweet or sour (if to the extreme I get some sense of it) I've had to redefine the sensation of hunger, also... as the nerves I guess that report this are also now squirrelly? So while it doesn't feel like the old hunger feeling, I use it as a new hunger signal. . . though it's very close to feeling nauseated.
