Paying for Cymbalta can be tough. I don't know if it will make you feel any better, but at the moment in the US, the generic version is only a tiny bit cheaper than the name brand (like $20-$30/month.) The projections that I've seen say that it should be a lot cheaper in another couple of years.

I don't know how much Cymbalta costs in Canada, but right now in the US, it's typically in the $250 ballpark for thirty 60 mg capsules.
