BS”D
For indigestion and gas (of the morning after a simcha variety); activated charcoal flushed down with real mineral water. For this I drink a 500ml bottle of Borjomi water from Georgia (Gruziya) which is available in Brighton Beach, and along Kings Highway in Brooklyn as well as from Raskin’s Fruits in Crown Heights. Here we buy activated charcoal in any pharmacy but I think you can get it in health food stores in the US.
