I have the same condition like you. I managed my heartburn right away by eating alkaline foods. I like to share my story with you guys that I'd overcome my fecal odor, by drinking a probiotic drink. After 2 days of drinking, I began to feel a flu like sick. I had semi-watery phlegm. I had chills, but I still continue drinking the probiotic drink (3x a day). After a week my probiotic drink was out. So i had to stop. now, I'm a happy man. my fecal odor smell was gone :)
