A word to the wise - not necessarily new, but good

Efficacious: capable of having the desired result; effective. Used in a sentence/paragraph:

I, Gr. Barb, still believe in the efficaciousness of my LOSE/WIN challenge: i. e., (1) eat anything I want, just in smaller quantities, enough to eliminate any hunger pangs; (2) get as much exercise as can be tolerated. But, here's the thing: believing in the efficaciousness of something and actually BEING efficacious have sort of parted ways in my case. I seem to feel it necessary to consume more than I did - in the early months of my challenge - in order to assuage those very persistent hunger pangs ("pangs" is a titch dramatic for what are really urges) (I'll maybe take up the word "assuage" at a later date), so that I haven't lost any weight for over 3 months, have remained at -40-42 for all that time. Which is not to be sneezed at, but I need/want to lose at least 40 more. I'm pleased to report, however, that I've been totally diligent about the exercise part. And here's the biggest rub of all: there are only two places that show evidence of those bygone 40 lbs.: my face (think 99 yrs. old) & my height (picture me 3 1/2 inches shorter). So, if anyone casually asks you if you believe there's justice in the world of weight control, you have my permission to answer with a firm NO.

So here's to EFFICACY (the shorter noun version of efficaciousness)!!!!
