Why has my stomach been burning? it burns when i wake up in the morning, if i don't eat, and when i drink wine.

Reflux or Ulcer: You may have gastric reflux or an ulcer. You should refrain from eating 2 hours before going to sleep. You might want to try a medication like Pepcid (famotidine) and then follow up with your regular doctor after taking that medication x 2 weeks. No smoking and minimize alcohol use. If Pepcid (famotidine) doesn't help, you may need further eval for an ulcer with your regular doctor.
