drowse off

drown drowsy drowning drowned drowsiness drowsily drowse drow drowing drown grief in drinking drown oneself drown oneself in work

go off half-cocked go off into go off into a doze go off into wild flights of fancy go off like a candle in a snuff go off like hot cakes go off like the snuff of a candle go off shift go off the air go off the boil
