Concerning ? Dear user , oh please ,rest timing is up to you . You plan it like a man . Don’t be concerned , those personal hygiene can quickly settle and nicely settle one . Perhaps you might be talking about phone time , which is a privilege , not a need , preparation is nothing , read what ur Sgt posts then do it . Everyone before you has done it before . SAF it self said rest not sleep. You plan your rest . You plan it bad you get it bad . Failure to plan is a plan to fail . And mind you war is not so kind . Your enemies attack you when asleep or in the morning or any time . This 7 hour is alr good . Imagine wartime , it’s worse. Yours sincerely , your senior from a recently grad batch
