I started dipping when I was 18 years old and a senior in high school. I continued to do it throughout college for 4 years and at 23 years of age, have just made the decision to quit for good. It has now been a week since I quit. It has been far from easy, but I feel my mental strength is getting better and better with each day that passes. The hardest part so far has been the massive headaches I have been getting. The thing that I am most thankful for is that sleep has not been too much of an issue yet, (although I did have a "dip dream" last night). I am glad that there is a forum for fellow quitters on the Internet where individuals can go for support and advice.
Thanks,
Alex
