After you've been on a PPI for a long time, you probably don't have heartburn anymore for the original reason. After I tailed off I occasionally have a throat spasm, but no reflux. If I did have significant heartburn or reflux again I'll definitely use an H2 blocker, and only for a short period of time.

Through trial and error I came to a low-carb(/low GI?) paleo style diet which seems to be inline with what other suggest. Alcohol, sugar and even stress definitely make it worse for me at least.

edit: Special occasions where I might indulge in the above triggers I'll end up using an antacid for a day or two.
