Where can I find these strips everyone is talking about... and what do the colours mean for Atkins and so on?

I'm not moving.. in three weeks again.. and I'm under 25 carbs a day.... I am feeling SO much better with this way of eating, but man I wish it would move a tad faster!

local drug store or walmart n the diet section. I do not use them myself

I had to ask for them - in our locals, they keep them behind the counter. I can't imagine why.
