Hi, I have gone through your medical history carefully and understood your concern. Stomach pain, nausea, chest pains and feeling weak are suggesting hyperacidity problems of the stomach (most probably acid reflux or gastritis). You report to drink beer on ice, smoke cigarettes sometimes at night. These are all aggravating factors to your stomach problems. Protonix is a proton pump inhibitor that will reduce acid production from the stomach. But it requires at least 2 weeks to take effect. This explains why you seem to feel worse. I recommend to add antacid mixture to have an immediate relief for your stomach hyperacidity. Take probiotics to stabilize intestinal flora. Avoid drinking beer or any other alcoholic drinks; avoid smoking cigarettes. Follow a healthy diet: no processed foods./ no spicy/ no chilly. Have your dinner at least 4 hours before going to bed. Have your meals regularly, do not skip. If still no improvement, upper endoscopy recommended further. Wish fast recovery.
