Magnesium sulfate / potassium sulfate / sodium sulfate
"Took my first dose 2 hours ago. I smelled it and thought to myself "this won't be too bad.. It smells like cough syrup!" Well, two sips in I was gagging like no other. It took about a half hour to choke it down. Instantly, cramps and the worst nausea I've ever experienced. Slowly a headache added to my problems and I've been miserable since. First movement just happened and yeah, faucet-butt that won't shut off! It definitely works. But I'm scared that I won't be able to get my second dose down."
