I've made it 22 days! The last couple days I have been feeling this tightness and being wheezy in my chest. Is this normal? I have also woke up to coughing which really worries me. I make myself crazy worrying about cancer. This has been so tough. Do you find that the cravings subside EVER?? Some days I want to cry lol. I'm glad I have quit I really am! If anyone has advice it would be so appreciated!!
