Mr. Lahtinen (former chairman of Finnish NLP) in his book Joogalento (~yawga-lenn-taw: Yogic flying) often mentions his craving for coffee.
Although my memory might not be as reliable as e.g. RWC's, I seem to recall that after doing siddhi-s at the now defunct local TM-centre, I sometimes drank up to four cups of coffee right after returning home; way too much for a hypertensive like myself. I think the reason might have been that my mind couldn't stand the extreme physiological, or whatever, relaxation (e.g. my feet feeling almost like rubber when walking, and stuff).
