You don't have a "habit". You are a nicotine addict. Biting your nails or not flushing the toilet are bad habits.
You are being controlled by a poisonous can of lies. Nobody NEEDS nicotine. Food, clothing, shelter...nicotine? Ummm no.
Everyone on this site is a nicotine addict. It's "been hard" for every single one of us. We all turned to the tin for comfort. We all thought it provided some sort of security blanket. You're not alone in those thoughts, trust me.
It's all lies bro.
Nicotine fills no voids in your life, it creates them.
"Only a few years". It doesn't matter. One is too many and 1,000 will never be enough.
It's time to stop "thinking" about quitting and step up to the plate. Time to REALL try. Not just put some gum in when you have a crave and then say "I tried, but its too hard". That's pussy ass shit.
If you are truly serious about quitting you need to make nicotine your enemy and not your butt buddy. You need to educate yourself on it and be ready to fight tooth and nail. You need to start building a web of accountability. You need to make a promise to yourself and your web that each day you will keep nicotine out of your system.
We can help you with all of that and more, IF you truly want to quit.
If you're too scared of leaving your security banky and would rather suck on the poisonous teet of addiction, then we cannot help you...nobody can.
Choice is yours.
