I'm having a lot of trouble with gas choking near my heart when I have dinner at 9 pm. It's making it really hard for me to sleep. Whenever I try to rest, I wake up feeling uncomfortable around my heart. I'm also smoking about 4 cigarettes a day. Could this be causing these issues? What should I do?

It sounds like you might be experiencing acid reflux or indigestion, which can cause discomfort near your heart, especially after a late meal. Smoking can also contribute to this. Try to avoid heavy meals before bed and consider quitting smoking for better heart and digestive health. If the discomfort persists, its important to consult a doctor for further evaluation.
