A patient are you a doctor ??
some states have tracking systems for that we do here in Ohio but right now it is only optional if you search into it....But I hear that in the next couple years they are going to make it mandatory to have these systems in every pharmacy nationwide.But I can tell you this is very common.
Your post makes me a little nervous I pray your not trying to find out the low down so to speak so you can not worry about being caught doctor shopping!!??!!
Please reply and tell me I am wrong but I felt huge vibes when I read your post.
