Last semester of college my acne got out of control; giant cysts right in between my eyebrows, huge red spots that took weeks to heal and the first of a couple scars. This lead my grades into a decline, my mood suicidal, unable to go out without thinking everyone was staring.

Just about a month ago I drank a whole pot of coffee to see how it would make me feel, and to my surprise my acne started to clear. I started drinking coffee daily, and after about two weeks you could only see tiny red spots where there used to be huge bumps.

Now I take 50mg of caffeine pills daily (tiny square in the morning) and the last of my scars are fading. I'm finally clearing up for the first time since childhood, and it feels great. 

Take note, it will affect how you feel at first, but after some time you shouldn't feel negative effects such as your heart beating heavily, insomnia, sweats. 
After a week of taking it it helps me to go to sleep, my mood is alleviated and NO MORE ACNE

Bump this post to help spread to others, maybe someone like me will benefit from this. And hey, I don't think it hurt to try everything to try and get rid of acne.
