Smoking and TTC

So I know smoking cigarettes are bad and not beneficial to our health. Now that we have established that. I smoke, I have tried quitting and am having such a hard time, I hate it soo much and wish I could snap my fingers and stop but I can't. I'm hocked and just don't know what to do anymore. I want to have a baby and TTC but need to cut this habit asap. What do I do? It's to a point that my husband even says I need to stop so we can TTC but it's soo damn hard regardless of how much I want to stop. Help? Any advise? I know it's bad but need help.
