Mark this one as failed. Yes, already.
I recently came to the realization that I may actually have something other than autism, and one of the ways people control that other condition until they get a proper diagnosis is with caffeine. And the most viable caffeine has zero-calorie sweeteners in it.
My next doctor appointment's in March, so given the process I think it will take to get diagnosed with this other condition (or prove once and for all that I don't have it) I'm not going to make the April deadline.
