While 3 mg's is a substantial dose, if you only took them for 13 days total you should be ok. I would call your Dr. or at least a pharmacist to double check. Hopefully one of the nurses on the forum will see this and can offer more insight. What was your prescribed dose or we they not prescribed?
This is a question for a doctor and im not a doctor but due have plenty of experience with benzos I would think your going to be fine 13 days is not that long you may not sleep for a wile but again always go to the doctor for medical advise good luck and God bless.................Gnarly
