A pdoc who specializes in addictions can help you, or you can even inquire if any local medical centers where you live have cessation programs, don't give up, you are doing the right thing by quitting. I got an idea, you can come here and talk to us when you feel like this, even check if anyone is on "chat", usually at nite you can catch someone to talk to
Your lungs will become healthier once you quit too, just like cigarettes, both are bad for your lungs and the other chemicals in both smokes affect your whole body in a negative way, so I am cheering you on

Good luck and take care,
