I called to refill her prescription because they're only six sleeping pills left, and the pharmacist said that that prescription should've been good until September it's only the end of July right now! She is only supposed to have one I'm night, I haven't given her any in the last two nights and she's been fine and has slept through the night with no problems. I did say something to him, and he told me to look up a good sleeping pill that I could get over-the-counter.
Because you confronted the son and he because defensive because of his answer back to you, maybe, just maybe the son is borrowing his Mom's sleeping pills. I could wrong.
