I happened to have just had a Subway footlong sandwich and a bag of Baked Lays , so I figured I would be okay . After one bottle , I was , so I temped fate and went for another . It got me drunk , but not to the point where I was woozy , wobbly , or slurring my speech . I did not even feel like I was going to give up my sandwich , but I knew well enough to pull back the reigns after that 2nd bottle .

Question: Why is the narrator stumbling around ?
Answer: They took some illicit drugs .None of the above choices .They are disoriented on the subway .They are boozed up .
