I Am On Two Pain Medications Every 30 Days, But

I am on two pain medications every 30 days, but am not able to pick it up one day before the cycle (30) days start. I go without during the night at 6am and 10 am. My husband goes to pick it up and has to wait 45 min, but prescription has been presented a week ago. The doctor lets the Pham fill only on first day of cycle. Why do I have to go without the night midnight day one till 10am of day one?
I have asked this question numerous times, but all I get is threatening letters. Why cannot anybody explain it to me.? Appreciate an answer. EN
