Magnesium citrate
"I have been backed up for a week or so I asked my mom what I can use for relief. She told me to try magnesium citrate. The 1st time I downed the whole bottle and nothing. I told my mom & she asked me did I drink water after taking it, which I hadn't done. She told me to wait 48 hrs and drink another one, followed by at least 2 glasses of room temperature or lukewarm water. I drank it at 8 pm, by 1 am I was awakened from my sleep by noises coming from my stomach I had never heard & an urge to, poot. Something told me to find a toilet, which I did, and that poot turned into a full fledged ka boom! This stuff gets the job done."
