HELP! Reflux issues!

I need some advise from mom's whose babies have acid reflux. I am 99% sure my LO has reflux and have an appt with the PED tomorrow to find out. What can I do to help relieve the pain? I've tried gas drops and gripe water and they don't really help. I have stopped eating dairy as well to see if she has an allergy but it's still to soon to see if that's the issue. I am breastfeeding but mainly pumping and bottle feeding cause she is very uncomfortable when trying to feed from the breast. I am becoming more and more frustrated with breastfeeding as well and have thought about supplementing with formula or changing to formula completely cause I'm not producing enough and have to go back to work in 3 weeks. For those of you who have babies with reflux do you breastfeed or formula feed and how is it working for you? Have the doctors given your LO medication or any at home remedies to ease the reflux? I just hate seeing her in pain and want her to feel better! Any advise is appreciated!!
