Help!!! I'm worn out

My nursing baby has pretty bad reflux and is really colicky. 
Her stomach hurts her but hungry or not all she wants to do is nurse. I guess for comfort. She won't take a pacie (I'll do any trick in the book to try have get her to take one?) 
I'm wondering what kinds of meds could I give to her for her stomach. Gripe Water isn't really doing it anymore. 
She is 9 weeks old. 
Help?!?
