If my doc wrote the same start date for two scripts, will I have any trouble filling the second one 30 days after filling the first one? She writes adderall scripts 3 months at a time for the 15th of each month. Except last time she wrote them, she wrote the same start date of 1/15/17 for Jan and Feb. I filled the January one on the 15th, I'm concerned Wednesday I won't be able to fill it.
