I smoked for a long time and tried to stop many times, but really not much luck was on my own. I noticed some stories to try to quit. My husband bought the patch for me to try, and I was very impressed with the fact that I do not really smoke feel the need to have a cigarette. This took about 17 days. Then I realized that my eyes were red all day, so I could see in my eyes dilated small vessels. Then one night, when I started the patch on my thigh (unavailability) itching more than usual. If the patch is removed the stain was swollen and very red, and burned and ached. My doctor diagnosed me with more use and I allergic to adhesive.
