Whereas his family wanted him to sleep off his confused state of mind, the burdened man spends his night time in 'sighs and tears.' I missed this in my first pass of commentary, but I reckon this is a simple allusion to Psalm 6:6: 'I am weary with my groaning; all the night make I my bed to swim; I water my couch with my tears.'
