Acid reflux tips!?

Anyone else's baby have acid reflux, what happened your baby!? My 5 month old was diagnosed at 7 weeks and it's only gotten worse. She was on Zantac, which didn't help much so she was just switched to omeprasole(spelling?), it's been two weeks and she is still up crying every hour. I feel so bad for her!! The only that the soothes her is to nurse and it's only temporary relief.

Shes EBF and has been trying oatmeal and/or veggies once a day for about 3 weeks.
