I have backups upon backups. When I'm due for refills, I have about a week or two of any given med, EXCEPT my HIV meds. I always have at least 50 days on hand, even when I'm due for a refill. My brain in a bottle I have at least 45 days on hand when I refill. My other meds I have abour 12 - 15 days on hand (depending on the med) when I'm due for a refill, and I refill 90 days at a time. I'm kinda anal about that just in case.

Years ago, when I was switched to biktarvy I still had a couple months of the prior medication that he switch me from due to side effects. I continue taking the old stuff well fill the new stuff. So I have about a three month supply which has come in handy because Caremark sucks.

My insurance company wont let me order them early to build up a reserve. They only give me a few days before it runs out to order them. Otherwise they reject the claim and I have to go throught a bunch of red tape, because sometimes they think it was filled when it wasn't. So I don't try to order meds early anymore.

I just recently had my first problem with my meds not arriving from my mail order pharmacy as expected, they didn't arrive with my daily medication supply!
I never did get e complete explanation of what caused the delay, I suspect that Medicare might have been part of the problem, when I got done to my last 5 pills I contracted selectRX to get an update, they said there a problem with a refill and billing, I was just told they wouldn't be shipped for a week, ugh, there are ways to resolve this of course, I could have contacted my provider, fortunately my roommate does have extra, so I didn't miss a dose!

I'm in California, medical covered mine med's.glad to be in California
