Genuinely concerned, need answers

Im sorry if this is the wrong place to ask, but last night (about 24 hours ago now) I had drank a lot of vodka, enough to get me to vomit (i was at a dangerously high bac), but now that a full day has passed and ive gotten food and water into my body i still am having stomach pain. I dont get hangovers or anything of the sort because of genetics, so this is concerning to me, could it be an ulcer?

edit: i am now getting nausea, and dizziness edit 2: the pain has been progressively worsening throughout the day, but it has been there since waking up
