Reflux baby

Dear all, I would like to ask for your advices for my 7 weeks old baby who has reflux which is disturbing his sleeping a lot. I am 90% sure that he has reflux due to symptoms I found on him from the last 4 weeks. Sometime he stay awake up to 10-13 hours n kept crying. It makes me feel pain to see how uncomfortable he is. He currently is taking Aptamil Profutura formula n my breast milk. I hand read article which mentioned about changing milk which is more heavy. Should I change to the special milk that contain Anti Reflux ? Any other suggestions to help my newborn sleep better? Thank you in advance
