I made biscotti tonight...

We are talking about cantuccini here, right?
Almonds are just fine. If you don't like them anymore, don't eat them that often - try out some other biscuits and then enjoy the classic cantuccinis again. I don't even like chocolate in them.
What you might try however is to add different spices like cinnamon.

I googled it too and just learned that they are also called Biscotti di Prato.
What I basically tried to say is that cantuccinis (or Biscotti di Prato) are a regional speciality that simply only exists with almonds. I personally think they are perfectly balanced in taste so I wouldn't want to change anything.
If you however still feel the strong desire to change something and personalize it or bring some change into the running system, how about adding different nuts, coconut flakes, maybe raisins, different kinds of chocolate (white, dark, milk ones), cranberries, other dried fruits or whatever.
Just be aware that they are no classic cantuccinis anymore.
