Hello Mike ! Would you like a drink ?   No , thank you . I had too much to drink yesterday evening . I had a bad hangover this morning . My head felt terrible .   Were you celebrating something ?   Yes . It was a friend ’ s birthday party . We drank all kinds of things-beer , wine and spirits . After midnight , we were even drinking cocktails !   It ’ s a bad idea to drink a combination of alcoholic drinks . You should stick with one for the whole evening .   I know , but it was a celebration , you Kwon ? I don ’ t think I ’ Ve see you drunk .   I usually only drink beer and I rarely drink more than a few pints .   You are a sensible drinker . Anyway , I ’ m not going to drink any alcohol this evening . I don ’ t ’ want another bad hangover .   Let me buy you a soft drink then . How about a coke ?   Yeah . That ’ s a good idea . I heard that coke was first used as a medicine .
