"i had bad cases of blackheads and i wanted to be acne free for my graduation. i started taking this in december of 2012. my skin was clear, i was happy, until february of 2013. my vision started a black veil curtain effect, i would get severe dizziness. went to the eye doctor, got sent to a hospital, they didn&#039;t know what was wrong with me, all of a sudden i got something wrong in my spine  andnstarted crushing my brain and eye nerves. i got 3 lumbar punctures and a medicine called diamox. i got worse and worse and one day i said screw it, and i stopped taking everything. it all cleared up and went away, however, i now have nerve damage in my back and the vision and dizziness will never truly disappear. effective meds, but at what cost you should ask..."
