There is a support group called RISA (Refluxing Infants Support Association) who are wonderful for this. I called them. They can send you out information on how to deal with it and also are there for a chat whenever.
Do you sit your child up more when bf? That can help. Also, we raised the top end of DDs cot with phonebooks under the legs.
One of the lady's at RISA said to me not to give up breastfeeding as all Ill end up with is a formula fed baby with refulx. It doesnt change a thing. Keep going, you are doing great.
By the way, my daughter was on daily doses of a medication like Losec and it helped a great deal with the pain. Didnt stop her throwing up, but at least she wasnt hurting. I hope you both find something that works for you. I totally understand what you are going through.
