Saving calories for night snacks??

I am a nighttime snacker so I always save calories for after dinner snacking. I wouldn't be able to stay on track if I didn't save the calories for the evening.

Before I began this journey one month ago today, I ate at night. Then I developed heartburn and acid reflux during the night. It was unbearable, so my solution was to take a Nexium every day. Now since ditching nighttime eating, I haven't taken one pill and haven't had any heartburn. Is anyone else bothered by indigestion from eating after dinner?
