Interesting how I started ... I was 27 and I had really bad allergies and at the time my solution to sneezing was to take Benadryl, which had the nice side effect of making me REALY tired. One day, I was commuting with my buddy who chewed Copenhagen and I just couldn't stay awake, so I asked for a dip and low and behold, that miserable taste kept me awake for the rest of the ride. Fast forward 13 years later and I still chew, despite the advent of non-drowsy allergy medicine which I now take.
I decide to quit right before my 40th birthday ... I had started to suspect that it wasn't just a tool to keep me awake when playing video games, producing music or programming, that I was probably addicted. I also noticed that it didn't really make me anymore productive, nor did it help me focus on the task at hand.
I am 5 days in and struggling a little bit, because my weekends usually revolve around a lot of computer and xbox time which was prime chewing time. Not having it is causing me to pace and wander around as if I can't focus without it. Luckily, I now realize that and these thoughts just further reinforce my desire to quit because of how insanely addicted I am now realizing I am. I read through all of the posts, describing things THAT I HAVE DONE, like sneaking dips in the shower, staying up late to have a dip and now in retrospect I realize what an ass I was.
I am positive I am going to stick with this, especially after finding the site which absolutely reinforced my resolve.
