Ugh, I had it terribly with my second pregnancy. Especially the last two months of the pregnancy. I ate small meals instead of big ones but more frequent, I limited water/liquid before bed, ate grapes as a refreshing snack at night which didn't bother the heartburn and ate a lot of tums.
Here's an article that may help:
