Why my LPR didn't get worse after 5 days of alcohol, pizza,... ?

I’ve been dealing with LPR symptoms for about 4 months now (tight throat, throat irritation, globus sensation, bad taste in the morning, and occasional chest pain). Since the beginning, I’ve been very strict with a low acid, low fat diet and I’ve been taking Gaviscon regularly.

Recently, I went on vacation for 5 days and honestly I ate and drank whatever I wanted: several alcoholic drinks every day, pizza, etc... I expected my symptoms to get much worse, but surprisingly they didn’t change at all.

Is it normal that my symptoms didn’t worsen even though I completely stopped the diet for a few days? Has anyone else experienced something similar?
