Constipation
"I take this occasionally for really bad constipation.  This stuff works when nothing else works!  However -and this is important to note, it&#039;s uncomfortable.  As soon as I take it, I feel somewhat nauseous for several hours, and my heart rate spikes to a worrisome level.  You have to relax and force yourself to hydrate even though you won&#039;t feel like eating or drinking anything.  Because of the heart rate, it has sometimes given me insomnia too but I don&#039;t think it does that to everyone.  It is cheap &amp; effective.  It&#039;s fizzy with a strong lemon taste and a weird aftertaste.  I agree w/ others that you should take a day off &amp; be ready to run to the bathroom several times."
