I'm somewhat addicted to the strips as well, so it's not just you! Mine are usually in the moderate area unless I drink more water than normal and it will show more of a lighter pink. You may want to try cutting back on carbs for a couple of days to see if it makes a difference in the stick. But if you're feeling smaller and are losing, I think you could be just as satisfied with a lighter pink stick! Any amount of pink says you're in ketosis, after all, it doesn't have to be purple... (But it seems more exiting when it is....I know... )

Also, here's a tip my mom gave me, cut the strips in half! They're expensive little buggers and then they'll last twice as long.
