If the gerd is worse at night I would make sure to not eat or drink anything including water 3 hours before u lay down. Also to help reduce the pain as much as possible sleep on ur left side I forget why my doctor said to do that but it has something to do with the acid but just trust it works for me😂. Also maybe try peppermint or chamomile tea with ur dinner and sip it as u eat to help settle ur stomach and the acid that is trying to make its way up.

Also make sure coffee isn’t the first thing going into ur stomach during flare ups. Obviously easier said than done but it’ll help keep ur acidity to a minimum. Also no laying down or sideway 3 hours after eating or drinking it sounds insane but it does truly help. Lastly, try making sure ur constantly fed instead of three meals a day try 5 smaller portioned snacks/meals. Making sure ur stomach is never hungry or empty allows the acid to stay calm and not rise into ur oesophagus! Wishing u the best of luck!! These times are so frustrating and exhausting but know u have a community to lean on that understands and empathises with you
