Normally the success rates for fundoplication range from 70 to 90 percent depending on the study. Thus, this is not a fool-proof procedure. Studies also show that 60 percent of people who undergo fundoplication still needs to be on anti-reflux therapy.
It may also be possible that it does take a few months for improvement to be felt.
If there continues to be symptoms, you may want to consider 24-hr pH study to determine whether there continues to be reflux. If positive, there is a possibility that the surgery may have failed and options to correct this can then be discussed with your surgeon.
Glad to know you are seeing your Dr. next week.
