Hi J2K,
Sometimes reading too much of that stuff will actually cause it to happen more. Don't let reading that get you all worked up!
I quit smoking a year ago, but smoked heavy for 30 years before that, and yes, I did have a few heart palps, and sometimes my heart did a few flip flops. (like it skipped a beat) I know that is always scary stuff, but I wouldn't be surprised if your anxiety about it is making it worse. Try to relax. That's a really nice thing about quitting, a lot of those worries about our smoking and getting diseases from it, go right out the window with it!

And yes YOU CAN quit smoking! Millions of people have quit, and you can too.

How bad do you want to quit? If the desire to quit is there, then you can do it. There are several different methods to quitting, and we all have to find what works for us. For me it was patches and nic gum. For my husband it was nic gum. Some ppl, like toneighty up there, go cold turkey. There are inhalors, lozenges, hypnosis, classes, etc. And these support groups online can help you as well. Pick a quit date, and start planning how you will do it. And then do it. You will be surprised when you realize that you had the strength to do it, I promise you that! Dig deep, and you will find that inner strength in you.
Good luck!
