Did antibiotics or lack off food reduce my acid reflux symptoms?

ihave acid reflux or gerd whatever you want to call it and a week ago i went to the dentist to get my teeth removed so i had been put on penicillin and vicoden since i was on and went through my medication i i havent coughed i was assuming because i wasnt even able to eat or drink soft drinks i rarely spit since i used to spit when phlegm would build up and now im off the meds and when i eat or drink the coughs that would usually be caused by the acid have just vanished and ive been dealing with these coughts for years is it the antiobiotic that had an effect or is it the lack of food since i couldnt eat while my teeth were healing
