If you've done stuff with logic and theory of computation before, the opening of GEB is not terribly difficult, and it will pull you through to the next parts. If you haven't, you might consider it a fun introduction to the subjects that you would have to read more slowly.
The upside is definitely worth a few reading struggles. It's one of those once-in-a-lifetime books (by which I mean that you don't come across books this great often; I don't mean you should read it once and throw it on the fire).

I encourage you to give it a shot.
