Can I ask why you want to stop taking them? After a week, you haven't even gotten enough of the drug in your system to tell if they are working or not, it takes at least a couple of weeks and sometimes up to 6-8 weeks for the full benefit of the drug to be in effect.
Of course it is your decision to stop them or not, but I wonder why you want to stop taking them so soon, are you having side effects? Oh and welcome to the forums.
