Magnesium citrate
"I have to say I didnt beleive when i heard this worked inmediately.....I am usually very regular but after 6 days of constipation I was in hell, being bloaded and gassy is not the most pleasant feeling. So after 3 days of looking at the bottle i was still afraid it would taste like cough medicine but i was desperate so just drank it.... no bad!tastes like soda.... so drank half of the 10 oz  bottle n then a bottle of water after 1 hour felt nothing but nausea since i drank it on an empty stomach at 9am....30 mins after i drank another 1/4... 1 hr later i thought maybe hot coffee will help.... i didnt even finish my coffee when i felt ready... so 1 hr n 30 mins for me!no cramps or anything.... better than pills! this stuff is magic"
