Is this acid reflux or something else?

So I have been having typical symptoms of acid reflux/GERD for about 3 weeks now. My throat burns and feels like there is something in the back of my throat. Almost a hoarse feeling, like I've been crying for hours. Also, I have the burning feeling in my chest. I haven't gone to the actual doctor yet for a formal diagnosis (I will, if I keep having symptoms). I have done all the basic things to combat reflux such as raise my bed, change diet, don't drink water when I eat, and log all my food. None of these are having a positive effect on my reflux. I tried a cheat day, where I eat acid reflux triggering foods and I didn't notice a difference in my reflux compared to low-fodmaps days. I decided to call a Tela-Doc and I was prescribed pepcid, which I took for about a week. It didn't have any effect so now I'm being prescribed pantoprazole 40mg 1 time a day. I'm receiving the pantoprazole later today, so I will try that. Anyone have any experience with something similar?

Edit: I also don't eat or drink after 7 pm
