Brief Answer:
Hello. This isn't from the Gaviscon

Detailed Answer:
Hello. PeptoBismol can cause black stools, but not Gaviscon.

Black stools imply an upper gastrointestinal bleed as with gastritis or a peptic ulcer.
With your reflux symptoms, you need upper endoscopy to check for either of those causes and the bleeding needs to be treated since you can get seriously anemic if it continues.
