Jan, how long have you been on your plateau? Some questions for you...how many calories are you consuming a day? Try...and you're going to think I'm totally off my rocker...try upping your calories for 3 to 7 days, to maintenance level. Then go back to your weight loss level and see if that works for you.
The other option is to kick up the activity a notch or two...
And bluebird? An occasional candy bar is perfectly fine! In fact, it's necessary for good mental health! ;) For real!! If you deny yourself totally, something you **really** want, then sooner or later you're going to give in and eat six of them! Better to tell yourself you can have, say, one a week...and then enjoy it completely without guilt! ;)
