I survived 32 grams of tylenol (acetaminophen) and 400 mg of omeprazole without medical attention. can i survive having 2 grams of omeprazole at once?

No: You need to only take medications as medically prescribed and recommended. You need to see a dr. Asap for counseling and treatment. Call your local emergency department and ask for guidance to a crisis center. Taking that many pills and such large quantities is not healthy. If you are not suicidal, than at least call your dr for an appt and a full medical evaluation before taking any meds.
