Many people have the idea that after 7 days of quitting nicotine is out of your system so therefore it's all mental after that. I totally do not agree with this analysis. For one we have built up receptors over the years to house nicotine and these receptors are waiting for the nicotine to give us our jolts. These don't just go away overnight IMO. I think that the longer you quit they start to go dormant but it takes time. I think I had a lot of ups and downs until about 100 days or so. After that it gets much better. Hate to keep saying the same answers on posts here but keeping active is the #1 thing you can do to keep from having so many ups and downs with the quit. Sometimes it takes dedication to go but for me it made a big difference. Your doing great. Here's hoping those ups and downs go away soon. Your cruise is coming up soon, wow!
