What's the right method?

So I have an appointment with my PO on the 21st. I stopped smoking 3 days ago, and I'm eating zinc, niacin, vitamin B, and vitamin C in the morning and at night on top of drinking nothing but water. I've been a daily smoker for about 2 months with a few short breaks in-between. I smoke mainly flower, but have hid a pen a few times and a couple dabs within the 2 months. Would Certo, qcarbo, or detoxify work for me as a 6'3 180lb male after being clean up until the 21st? Or should I just chalk it and tell my PO I fucked up?
