well, mine didn't. (different states, I guess) -

and it is an allergic reaction, not often everyone have that. you said you started three weeks ago, I got hives just two weeks after I started then the day after I started hives, my throat swollen and I couldn't breath. are they big or small hives, it started yesterday or today? but please watch out for the next few days!! I don't think you should keep taking it either way.
