I use zinc 15mg, no other vitamins. In case i binge, i usually have a 5 day window after when urges are minimum which then slowly start getting stronger. This is without zinc. If i use zinc the 2nd day, by the 3rd day the urges start getting stronger and the peak at 7 days is very, very strong. Srsly. But the benefits come faster as well and are more pronounced. I found this quite interesting, especially as it happens with such consistency.
