I had three endoscopies and they weren't as bad as I thought they would be. You both sound like me in a lot of ways. I had the Nissen because I grew tired of medicines, restrictions, and such.
Moderation is key with most anything. I was a frat boy, so trust me, I know how you feel. How is your weight? For now, you may want to try eating a little healthier and drinking a little less. It's good to avoid things like chocolate, peppermint, fatty foods, citrus fruits, tomatoes, etc. Don't eat late. After you eat, wait a while before you bend over, recline, or lay down. Maybe see if that helps.
I ended up thinking something was up because of a fluttering feeling in my chest. Like anyone else, I thought it was a heart issue. I had Stage 4 esophagitis, a hiatal hernia, and GERD. Barrett's esophagus was revealed later. I'm currently struggling with my surgery six weeks in, so I'm hoping for better days.
I hope this helps.
