I took it to The Medicine Shop today and according to the Pharmacist, the pill is a form of Ritalin... but even they were unsure as the markings did not match the 2007 id book.
Thanks for the help!
I thought it pretty odd when I picked up my Rx the other day to find that my Ritalin looked different. I've never gotten the greenish blue round SZ/789 pills before but when I looked online for the reason why, I didn't find enough info to draw any conclusions.
Perhaps, coincidence is enough to convince you. If not, I'm sorry I could be of more help.
