How many days does the one on 9/15 think the meds will last you? If you are thinking it is okay then why don't you just order from the same place?
If they both use the same dr and pharmacy, its like using the same place all over again. If you can take 4 a day and you got 60 pills, then that is only 15 days worth. I did not think those places wrote for 4 a day. I thought it was 60 or 90 and they were expected to last you the month????
Someone who uses them should be able to answer you.
Call them and ask if you are allowed to take 4 a day and explain by doing so you will run out in only 15 days.
