Partner had nasal cancer surgery last Wednesday using endoscopy , he came home following day but since then is not sleeping at night and is complaining of pain in his face , he also had his teeth removed so is on soft food diet . He's a smoker who's unwilling to quit . He is very lethargic during the day , sleeping on and off every few hours . IV suggested he goes to g.p to ask for painkillers and perhaps sleeping tablet , is there any other help or advise you can give . Thank you
