Elise,
You didn't give the Advantage enough time. It really will work, if you will follow the information I gave you above in the post.
It takes about 2 months. I know it's hard...and you want to get rid of them right away, but "overkill" won't help. Just be patient and use the Advantage as directed and you will be flea free.
In the meantine, if you have problems with fleas jumping on you, use a product from AVON, "Skin so soft" and it will keep them off.
