Minocycline
"This medication is incredible.  The ONLY side effect I experienced was mild nausea, which after the first week seemed to subside quite a bit.

I am currently on 200 mg/day--(two 100mg tabs)
Starting out my acne wasn't quite so severe, but I did frequently get cystic acne which was painful (which was why MA Health agreed to cover the cost after my MD petitioned them.)  I've been on it for about a week and a half, maybe two weeks, and I've already seen the difference! 

This is my second time being on this medication--I was prescribed it in 2014, I don't know what the dosage was at the time, but after about 2 or 3 months my skin became totally clear the first time around, and before I started that time, my skin was in much worse condition."
