smoking cessation
"I am into week 3 now, haven't had a smoke in a week. When I was smoking, i became very ill. I still get very sick to my stomach, dizzy, constipated, gas, metallic taste in my mouth, everything           smells bad, and my skin is super sensitive. I don't think I would have been able to quit without it, but I don't think I need it anymore."
