The educated guesses ranged from 6 weeks to 1 year to fill a 100oz hard-sided plastic, liquid laundry detergent container with used Copaxone syringes:
Shawna said 6 weeks (42 needles)
mdmhvonpa said 2 months (60 needles)
Jeri and Miss Chris both said 3 months (90 needles)
Diane more explicitly said 13 weeks (91 needles)
And insulin-dependent Aprilmoon said 1 year (360 needles)
In repeated experience, it has taken a full 9 months to fill a laundry bottle 'sharps container' with daily used syringes previously filled with Copaxone. I once tried to stretch it to 10 months but was unsuccessful in the attempt.
Without further ado - drumroll please
The winner of the Trivia Question and the 'Sensational, Sharp, Smart Blogger Award' is Aprilmoon who said it would take one year to fill the container with syringes. Although a 1-year estimate exceeds the actual experimental outcome, it comes closest to the correct answer. Perhaps the syringes used for insulin are a tiny bit smaller than the ones used with Copaxone.
Congratulations and please collect your Blogger Award.
