I had my gallbladder removed in August 2008 after having two attacks. I have had no problems since except for the last two nights I've had chest pains and nausea. It wakes me up in the middle of the night. Is there something else wrong with me or do I just need to adjust my diet? I've been scared of having a heart attack but kind of figure that's not it since I'm taking a daily dose of folic acid and baby aspirin.
