Yep, that was due to the Epsom Salts . That's one of the reasons why I don't use it- I like to sleep through the night without getting up constantly LOL! :) If you want to keep using it cut the dose in half and you should be okay. :) Or just don't use it. If you don't use it, take extra special care to use stone dissolving agents like ACV, GCG, phosfood, malic acid prior to flushing. :)
