I used to have mad reflux back in the day eating more than 5000 cals in one sitting, but I have a few tricks now which may help ya. First, end your carb night way before you go to bed, like 2-3 hours at least, if not more. If it means stuffing yourself faster or choosing softer/denser foods, so be it. Second, go for a slow walk right after eating or at least stand up. Lying down is the last thing you wanna do, even sitting back too much makes digestion slow down. When I really overdo it I'll have an anti-acid tablet or something, but that's crossing into birthday binge territory only 😛 Finally, you may not feel like it, but drink some water and do not go to bed before feeling ok lying down, like stuffed by not nauseous. If it means going to bed later, then so be it. Your sleep will be better anyways.
