I am doing a maintenance flush tonight. Fun! (No, not really, but I will be glad I did this tomorrow.)
I make my Epsom Salts in a glass pitcher and cut up lemons and it's so pretty.....looks like lemonade. (Oh well, a girl can dream....)
I ALWAYS use straws for the Epsom Salt and then the olive oil/grapefruit mixture. You don't even taste anything.....well, not exactly, but the straw does help.
I also like to listen to Fleetwood Mac and Bob Seger while flushing. That helps, too.
