Thanks for choosing health care magic for posting your query.
I have gone through your question in detail.
it is not practically possible for someone not to sleep for even 72 hours. Probably he did not have a satisfactory sleep cause of his depression
and he is exaggerating the symptom cause of his depression. He needs to show himself to a psychiatrist
who can start him on some meds so that his depression comes down and he even can sleep well.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
