I didn't think it could be done.
You were replenishing it per instructions? You can certainly exhaust a single bath by printing but it takes a lot of printing. I normally discard it from time and don't print enough to wear it out from use. I've kept a working strength bottle mixed in September and made prints in January that were _almost_ indistinguishable from prints made with fresh working strength mix, though it took it about .25 grades more contrast IIRC (required splitting exposure between filters for closest match.)
