You didn't break any rules, but notice how everyone jumped on a simple truth. You are so close to your treatment period, that even if you did NOTHING, you would feel better every day as that treatment gets smaller and smaller in your rear view mirror, even if you took nothing.
But if it makes you feel better, and it is part of a new awareness and healthier living regime that you are on.... go for it. Just remember that vitamins are vitamins, and if their available active ingredient is the same you don't have to pay exorbitant prices for them. Besides the fact that your body is coming out from under a time of extreme duress, and that alone will improve your wellness every day, don't discount placebo effect. If you believe enough that these are doing it for you.... (and you have the $ to toss at it) what they hey - if it makes you feel better to do so.
