I've never used nicotine (except in the form of chewing tobacco a few times while playing softball many years ago). I stopped drinking alcohol in February 1978, when I was 20. Eight days ago, having drunk coffee (and tea) for about 36 years, I gave up caffeine. Please don't write to say that alcohol is a depressant rather than a stimulant. That may be so for some people, but it never was for me. Alcohol was as much a stimulant as caffeine, indeed far more so. Which of the three stimulants do you use?
