"Addictive" is a strong word with all sorts of negative connotations. That said, I have found it strangely difficult to stop it for long periods of time. No problem for a week or two, but then, to quote a song, "and you know that notion just crossed my mind." I get a little antsy, and I start to feel an impulse to take a little. I especially miss the sense of calmness, and the sensations in my breasts and nipples. In any case, the urge does not feel like it is based on reason or logic; it feels much more emotional, visceral, and like a compulsion. It is more right brain than left brain. So. . . perhaps the word "addictive" is not really wrong, just a little disturbing.
Do others have this sense as well?
