I wanted to try these patches because I thought I needed a little extra help trying to quite smoking. They were pretty expensive, but compared to buying cigarettes all the time, it would have been worth it if the patches worked. I hated the fact that I couldn't still smoke every so often while using these. I had a really hard time keeping the patch on. My skin was clean and smooth, but the patch kept falling off. I ended up taping it to my arm. These didn't work at all for me. When your so used to smoking, a patch on your arm will just not replace it at all in my opinion.
