I keep a small Excel spreadsheet to log my vicodin intake. For each refill from my doc I track:
- Date of refill
- Date of first dose
- Date of last dose
- Number in refill (always 45 at the moment)
I then have a few columns to calculate:
- Daily intake from refill to refill
- Daily intake from first dose to last dose
I track both of those because I usually leave about two weeks after my last dose before I request a refill (just so I know I'm in control of the meds and not the other way around

) So, for example, my average daily intake, first to last dose is about 2.1 5/500 tablets per day. My average intake, refill to refill is about 1.4 5/500 tablets per day.
Most important, I watch the trend. I'd like those per-day numbers to stay flat because my although my back condition (disc degeneration) is not improving, nor is it getting appreciably worse. Since the numbers *are* indeed flat, I'm concluding that I'm taking sufficiently small amounts that my body is not developing any kind of tolerance, or if it is it is very very slow in build up.
Anyone else do this kind of thing?
