Usually withdrawal symptoms will only last for 8-12 weeks, but it also depends on how heavily you are addicted, your constitution, and your life's situation. I don't think you should have too many problems for this long.

You may want to try a detox program at this point, or look to other circumstances that may be causing your anxiety....it could be that it is only coincidental that you noticed these symptoms of anxiety when you quit smoking when they are actually due to other causes.

I totally agree with Mominashoe! I smoked 2 1/2 packs a day for well over 14 years. I quit January 28 1991.........hardest thing I've ever done in my life, but I took control. The anxiety you are feeling is normal, you do need to try to find something to do with all this extra energy you now are having! I crocheted, cross stitched, worked in the yard, played with my animals........ If this continues, I'd see my primary care physican just to rule out any other possiblities. So proud of you for kicking the habit............HUGS!

I keep on failing at that...GOOD ON YOU!

I also get anxiety...or rather "hightened" anxiety in my case when I try to quit.
