I definitely agree with Kitt that everyone is different. If I eat a spicy food, it hits me within the hour, and depending on the spiciness, it can cause anywhere from intense pain to normal, run of the mill heartburn.
I also believe it's possible for one little mistake to throw you for a long period of time. I haven't had GERD for a week, but last night I ate just a little too much and I was up all night. This week, I know, my stomach will be extra sensitive to things I've built a little resistance to. It feels like I'm backto square one.
Perservere, friend! I hope that since we haven't heard an update that it didn't bother you at all :)
