In Canada, the stix are with the supplies for diabetics. They used to be behind the pharmacy counter but are now out on the shelves in Shoppers' Drug Marts. They cost about $7.50 Canandian. I hear that Wal-Mart in the US has them. The most common brand name is Ketostix by Bayer.

And the interesting odour is less expensive. If you are losing, why bother with the stix?
