I am 18 days clean of opiates. I too had horrible chills, lasted a week for me. My daughter is 3 and a half, and I to feel guilt for being addicted to pills most of her life. I try to use her for my motivation to stay clean. I also have not smoked pot or ciggs in 18 days. I don't want my daughter to smell like a ciggarett, have memories of me smoking a joint, or resent me for being high throughout her child hood. I resented my own mother most of my life, I want to break the cycle. I have signed up for college and qualified for pell grants. My goal is to get my life together so my daughter has a good role model and a good start at success. Good luck, you got this!
