breaking b/p cycle

I’ve heard that a way to break the cycle is to keep a binge down but the last time I did that it took over 48 hours to fully digest. I was in so much pain with my acid reflux and stomach in general and I could barely drink anything bc it felt like my stomach would explode (or regurgitation) for hours. I’m scared to try recovery bc when I keep anything down that isn’t a small meal I feel so much pain. I was wondering if anyone else deals with this, and if they know the best way to go about recovering when it feels like your digestion is slowed?
