Acis Reflux or Colic Baby

Hi parents..i need help...im so down right now.. Itz juz me and hubby taking care of our baby..when hubby at werk i will b alone taking care.. She's 1mth plus..since day 1 she have been vomiting milk..went to PD and diagnosed wif acid reflux...been given probiotics n motilium.. Previously was on Enfamil Pro A+ then now Nan Supreme Pro HA..she still vomits milk..quite a lot till from her nose..n at times constipated..her poop will haf mixture of paste n squishy poop... Shes been cranky.. especially at night n whatever we do for her..like bathing..diaper change..she will cry..she crys alot wen shes awake.. We did burp her halfway on her 120ml feed then once finished will burp her again..we let her in upright position for half hr..adjusted her cot to be slanted.. elevated pillow too.. numerous tries of different rubs.. What do i do? Im confuse if shes colic too... But so far..She never refuse milk..do i change formula again? What formula? PD wans to recommend NAN AR but afraid it will make her constipated due to e starch...dun noe wat to do oreadi..some frens saes itz normal till 3mths...
