Does anyone know the true cut off day for..

Picking up your meds? I know for the habbit forming ones, some pharmacies let you get it one day ahead, some you have to wait that day. I think mine lets you get two days head so your never short, however I always have extra xanax based on my rule of stopping to think first. So ..............I wonder if I should try n get it today Monday, and retrieve it out of the system two days early, I wonder if the owner will let me. He and I are very good business associates. He's been my guidence in this medication for over 20 years. When that one man denied my pain, and my pain meds, he wasn't fired. Till I told the owner I will press charges the next time he tries it, because the Hippa Law was broken on his part twice by his denial to refill. They cannot refuse your meds based on their opinions if these are safe chemicicals to use. THey did not prescribe them. THe user is already aware of the dangerous side effects, and reacts accordingly. I appreciate that he cared enough to question me, but not enough to help me.
