I have no idea what will happen if I stop taking them. I'm definetly sticking with it through the holidays, and maybe after that I'll try 1/2 bottles. I want to see how going a week without any would affect me, to make travelling and stuff easier (I don't want to have to bring bottles with me). But, I'll wait until after the holidays to find out.
I think the BIO-K is a Canadian company, so I guess that makes sense for it to be cheaper here. Is there any equivalent in the US?
