Is this AVR sleep code correct?

Yes, that is what Im trying to do, keep it awake. So I could either add it in the sleep() function after it wakes up:

void sleep(int ncycles){  

 nbr_sleeps ++;
 set_sleep_mode(SLEEP_MODE_PWR_DOWN);
 power_adc_disable();
 
 sleep_mode();

 // CPU is now asleep and program execution completely halts!
 // Once awake, execution will resume at this point if the
 // watchdog is configured for resume rather than restart

 delay(1000);
 // When awake, disable sleep mode
 sleep_disable();

 power_all_enable();

}

or in the loop before it sleeps:

void loop(){
  Serial.println("will sleep...");
  delay(1000);
  // sleep for 8 seconds
  sleep(1);

  digitalWrite(pulsePin, HIGH);
  delayMicroseconds(1000); // Approximately 10% duty cycle @ 1KHz
  digitalWrite(pulsePin, LOW);
  delayMicroseconds(1000 - 100);
  
  Serial.println("pulsed led...");
  
  if (nbr_sleeps==99) {
    Serial.println("running motor...");
    runMotor();
    nbr_sleeps=0;
  }
}
