You are making me blush :) Running "partial" fail IN18's at up to 15 mA for several hours will SOMETIMES resurrect or part restore them, but I have not yet found this to be a long term solution. YMMV of course. At least, during this process, you can read a book (possibly even get a TAN) from the light your straining IN18 gives off. Else selectively assign them to tens- seconds, tens-minutes and tens-seconds roles, of course.
