My ex b/f had the same thing, burst ulcer from drinking. Nearly died. Since then he has been in hospital with bleeding from his oesophagus caused by varicose veins in his throat, caused by blood not getting through the liver or something from drinking damage.
It is like watching someone commit suicide in slow motion. He is also the father of my child and I can't bear my little girl watching her dad do this to himself. All the more reason for me not to drink!
