Acid Reflux Problems at night

Leia
I believe my daughter has acid reflux, constant swallowing, screaming when laying down, does not enjoy her swing anymore, and often spitting up (not unhappy though). I am not a big fan of taking medicines and would rather not go the Zantac route, but what would you recommend to help her feel better? 
She's constantly nursing, and I don't think it's making her feel any better, from what I've read it can make it worst.
Has anything worked for others??
