@lsy25 I'm sorry that you had such temporary relief after your surgery.
I've had 2 fundoplications, the first in '11 Nissen wrap then a Toupet wrap in 2017. The Nissan was done in conjunction with a GB removal (big mistake).
It sounds like you need some imaging or another EGD to check the integrity of the wrap. I hope you had a very experienced surgeon. The problem with these type of surgeries is that they naturally loosen up over time. I think that's what happening with me right now, trying to avoid taking PPI's (osteoporosis) & just use tums prn. Rarely drink ETOH, and even then I dilute it.
I would start with decreasing the amount of food you're eating at one time. Smaller portions. Do you have any triggers that seem to aggravate the reflux? I would avoid the citrus juices for awhile (like the margarita).
