The answer is built up piece by piece. Start with W for Women, then add an anagram (signalled by ‘nervous’) of ‘train e’ where E stands for east, giving ATERIN. Then come two words for ‘doctors’: GP (a medical doctor) and LACE (to ‘doctor’ or tamper with a drink). Together W + ATERIN + GP + LACE spells WATERING PLACE, neatly defined by the question ‘Where can one get a drink?’
