My father of 79 has diabetes and heart disease was fitted with two stents last year and also is taking hypertension drugs in addition to his anti depressant drugs and sleeping tablets but he just cannot sleep well as he complains his sleep is only four hours and that too not deep and full of dreams so is there anything in course of traetment or action required , he also has had minor transient ischemic attacks in the brain in past as per his last Mri.He is also on finesteride for his BPH
Please kindly advise
Thanks

Any and every treatment should be done with consulting his doctor, he has too many issues to try anything. His main doctor should be aware of all his medications. For many people with serious health issues, sleep will be short and more times of sleep needed. He will need to try to take naps and rest more often

Does he trust his doctor? Does he tell the doctor all this?
If I were he, I would be wondering about paradoxical effects sometimes seen in anti-depressants and sleeping medications.
But of course his situation is far too complicated to discuss online.
