One of the best thing you'll ever do. I have done it a few month ago after 20 years. I did gain weight so to offset it I started running 4 times a week, and lost over 30 pounds. I didn't do the patch, but for me the first 3-4 days were the hardest by far, then it become a memory very quickly. My advice, avoid alcohol for a month or so if you can, it's very big trigger. Best of luck.
