OP, become a HIS and work for a year or 6 months or whatever. If you like the field, get your degree. If you don't - move on. Best suggestion anyone can make to you. I wish someone would have given me that advice a decade ago when I started my Au.D. - I would have changed directions.
That's not to say that audiology can't be awesome, it just doesn't agree with my personality. But if I met a woman named Hearing Science Research I'd marry her even if she didn't drink whiskey.
