If I am 4 days clean off opiates will the withdrawal affects start over if I slipped and just did a little?

You likely will. Here's why. When people "slip a little" in opiate withdrawal it's like a woman being "a little pregnant"or a neurosurgeon "being a little off" when the brain laser is flipped on! Nobody "slips a little."...a "slip" or "little pregnant" or anything else means, you are off the program, the woman is TOTALLY PREGNANT, & the patient's brain is cooked. Your goal is 4 decades clean not 4 days. Focus!
