I have made sure to "save" a few meds from each bottle just in case there is ever a real problem with a refill. I have exact refill dates that cannot (or will not) be changed and so I just "short" myself on a really good day a few days a month. I keep these in reserve in a safe and am careful to never take more than I should. I have had several occasions when the pharmacy was out of a certain strength (especially with the xanax xr) and I have been able to save back a part of a bottle of the old dose. You can't break them, but my pharmacist knows me well and will give me a day or two of smaller doses to be combined into the correct dosage. Mostly, I'm just very very caution about who is in my house and who knows I take what to make sure nobody else gets any of my meds and messes me up. Thank God I haven't had that happen.
