Decided to take a tablet last night as I have mild constipation. It caused me to have the worst night sleep ever with terrible cramps and absolutely zero bowel movements so far. Honestly have has better luck with a simple laxative like dulcolax. Do I need a higher dose? Its the vitabright brand and it has 444 mg per 2 but I took just one.
