Suggest Treatment For Stomach Pain

Hi, my roommate has been telling me that she hasn t been feeling herself. She got really drunk on Saturday night and said she had a sip of someone else s drink but does not remember who or what it was. She has been complaining on her stomach hurting also. She has been unable to eat due to feeling sick. She does not remember significant events from that night and feels as though things are not real. She also says that she feels like time is not really going by. What should I do?
