Tough day

Though day for the ex-smoker I am. It's been a year since I quit smoking, wihtout too much difficulty. But today, for no particular reason, I keep hearing that voice in my head, wich usally go after a short while, urging me to buy a pack. But No, I won't, I can't, I Must resist!

"Even though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me."
