I believe it really depends on the person. My brother takes more than I do, daily, and he doesn’t get WD until day 2 cold turkey. I, however, take 15g a day, in 3 doses and if I take less, I get WD in between doses. So, I have to taper slowly to my goal of 6g per day. We have both been taking it for the same amount of time. I’m extremely petite, so I’m sure it could have to do with weight, but my brother is also not big guy. Edit: spelling
