Before I was aware of this site I was trying to quit and I went from dipping a can of regular Copenhagen per day, to just a few pouches per day. I'm 39, dipped for 20+ years, and overall in great shape. A few days in to dipping just a few pouches, boom, anxiety hit me. I'd have anxiety attacks about nothing. The anxiety killed my appetite. I also did a lot more walking, jogging, chores, etc, to burn off the manic energy. In about two weeks, I went from 206 lbs. to 196 lbs. I noticed the weight loss in my face too. I've been to the doc, and I don't have cancer. I'm also 90 days quit now and I've gained all the weight back. I would say, go see a doctor and talk about any concerns, that can help ease some anxiety. I would then tell him to join KTC, and put down all of the nicotine. We do not tolerate any form of nicotine around here. We're a Cold Turkey Club.
