When you've been doing something self destructive for some time (perhaps without realizing it) before something serious happens that forces you to come to terms with what you've been doing and that you need to stop.

He used to eat tons of junk food, stuff with all sorts of sugar, salty snack foods, you name it. It doesn't help that he rarely exercised.

Fortunately, he took it seriously and made a lot of changes to his lifestyle.

In the morning, or anytime of the day, when the victim is taking a shower you go into the bathroom and take a large smelly shit and then flush the toilet. By flushing the toilet, the water temperature changes causing the victim to run out of the shower and smell the stench filled air. Best done in the morning, hence wake up call.

You need find a random house, silently break into, locate random target, preferably female. When the target has been found, the aggressor then will be violently slapping with willy a victim over a face while she is sleeping. You are slapping her until she will wake up while singing "wake up call."
