Welcome aboard the Quit Train @Muddled Quince! I won't add musg more to what other wise quitters have already talked about. YES, you can do it if it's really important to you, which it now should be if you've been diagnosed with early stages of emphysema. Nothing but fresh air should enter your lungs from this day forward. It's not just a nice idea; it's now imperative and we can and will be most happy to help you achieve your ultimte goal 🙂 Stick around and post often no matter how you're feeling. We can help you put this fight and the challenges along the way into perspective. The turbulant times of quitting don't last all that long in the grand scheme of things and there is a whole world of benefits that will be yours aside from health improvements and money saved - like Freedom from being a daily slave to nicotine for instance - that's a biggie!!
Anyway, welcome and be sure to stick around!
