I'm using the patch to ease the physical w/d I'm having. Going through it 'cold turkey' isn't a good idea for due to other circumstances, but i would rather just get it all out of my system as soon as possible. I can tell you however, that the withdrawals I'm experiences don't seem to be THAT much different than most other people here. That alone tells me that most of the addiction is psychological. The hardest part for me has been not lighting up at all the times I usually would. At first, even though I'm using the patch, I was experiencing all the stuff you are talking about.
Most of the last 2 weeks has been JUST NOT LIGHTING UP when I usually would. And then my addiction started telling me in subtle ways that I should start smoking again. Last night I kept getting "Your life is so boring now that your not smoking". I just have to laugh at that because it is soooooooooo absurd! And then I was okay! Chewing gum and sucking on straws has really helped me a lot. Especially the straw! I just go through the physical act of smoking once or twice and then I'm absolutey fine. I swear it works! For the anxiety and depression, I get a lot of exercise! And hanging around here helps so much too. Especially when you can help some one who is at the same place you were at just a few days ago. It's amazing how much helping someone else eases my own cravings. Doesn't make a lot of sense, but it works for me!
Hang in there! You'll be just fine. I promise. Just wait and see!
