Hi Laura! Thank you so much for your great review. I'm glad you enjoyed it. As for your septic system concern, we actually recommend (on the website & label both) to spit it in the trash, first & foremost... Some people spit it in the toilet, and others the sink, but we also recommend on both the site & label, that if you spit it in the sink, to make sure you wipe it out, so it doesn't go down the drain... Many people (including us) have spit it down the sink and never had issues with their septic systems or drains, but there is that risk. We switched to trash spitting; we just spit gently, so it doesn't get everywhere, and it works perfect! :)
