My personal experience here is a bit limited - I grew up in the states but after college I emigrated up to Canada so... yea I generally get scripts from my gp up here for a full year's supply at a time and end up paying something like 1/30th of a cent (CAD) per pill for it. While I was in the states I had to fight to keep my script when I transitioned from my parent's insurance to my employer's in college, and ended up paying 9$/pill for a few months but I accessibility was always maintainable without ever seeing a psych except for initial diagnosis in middle school.

So... I guess I got pretty lucky on the whole.
