Magnesium sulfate / potassium sulfate / sodium sulfate

"I'm on the second dose, but it certainly hasn't been as bad as I was lead to believe.  I was done after 3 hours after the first dose, it's been 2 and a half hours since the second dose and I'm making less frequent trips. The taste wasn't great, but not as salty as I expected.  The second round seemed worse, maybe because I was pleasantly surprised with round one. No cramps so far, or nausea, the biggest drawback has been chills.  It's subsided after the first 90 minutes after each dose, but during that time I couldn't get warm.  I compare the taste to either old cough syrup or Ref Bull."
