I am on my sixth day of the nicotine patch. I am on the highest strength because I used to smoke a pack and day. Last night I went out and smoked while wearing it. In the last 24 hours I smoked six cigarettes. I have a headache now and I worried about having a stroke. I didn't realize it was that dangerous to smoke while wearing the patch until I looked it up today. I have taken off the patch for the next 24 hours because I don't want anymore nicotine going into my system which could cause more problems. Is it really that dangerous? Could it kill you?
