I mostly quit a year ago: Less anxious, less insomnia, less diarrhea, less headaches when I don't have caffeine. Didn't seem to affect me negatively in any area. The only times when I used caffeine in the past year was when I was sleep deprived(I rarely am now), and in that case modafinil is way more effective.
