Hi, Christine! Welcome to the community. It sounds like you've been through a lot these last few years, but I am glad you're here and trying to make positive changes for the future. It takes guts to do that. We have a ton of content here on the site that is focused on quitting smoking. Here's a link to check out some of what we have.

You have already gotten some great tips -- it can take some trial and error to find the combination of tools that work for you. I also like to remind people that it is perfectly normal for quitting to take several tries, or even many tries. I say this not to discourage you, but to give you realistic expectations so that you don't lose hope! You are not a failure if it takes time. Every quitting experience has something new to teach you. The key is to keep persevering, trying to learn and grow more with each day. Even quitting for a few hours has beneficial effects on your blood pressure! So stick with it and know that we are all here to support you on the good days and bad days. One step at a time! Hugs to you. -Melissa, copd.net team
