stopped smoking- how to manage flare?

I'm new here so I'll try to keep this short... I quit smoking in May 2011, had bloody bowel problem for months then went to get a colonoscopy trying to figure out what was happening- they also did a ct scan to check inside. they found a 2mm pulmonary nodule in my lower left lung but told me not to worry, come back in a year to get it rechecked .. dx'd with UC from colonoscopy at this time I had been quit for 1 yr and had no idea of the connection between smoking and UC. I started again and symptoms went away. I am on lialda. I went in for my 1 yr follow up ct last week and the nodule grew to 4mm. they are now referring me to a pulmonary specialist to decide on a course of action. I haven't had a cigarette since the ct results came back. Now I'm paying for it and my bowels hate me. please someone tell me how I can get this to a manageable state without smoking since I am scared about what's going on with my lungs. Can I eat something helpful? supplements? I'd prefer not to have to get on more meds right now... sigh. anyone BTDT? thanks for taking the time to read this.

thanks so much for the fast reply- it's not that I'm against meds it's just hard to get an appt and I was looking for something I can proactively do. I am changing my diet right now and cutting processed/soda etc. seeing if cutting junk food and pop will help some hopefully. Thanks for the SCD suggestion _ i hadn't looked into that. I have e-cigs but I'm scared to introduce any other chemical vaped or smoked at this time so that's out for the time being.

A fourth study[83] examined transdermal nicotine vs. oral mesalamine in treating distal UC refractory to mesalamine enema alone. Thirty patients were randomised to 15 mg nicotine patch or 800 mg mesalamine orally, three times daily for 4 weeks. Patients underwent clinical and sigmoidoscopic assessment at baseline and at the conclusion of the study. The remission rate in the nicotine group was 80% compared with 33% in the oral mesalamine group.
