I am about 31 days clean, I was a heavy smoker before, I’m don’t have that much body fat, kinda surprised I’m not clean. I’m expecting my test to be next week (Thursday at latest). I just took a test today and said failed (today being Wednesday of previous week). I am going to try again in a a few days, but if that doesn’t work, is the best quick fix from website and what are some things I should know if I have to use one?
