Try drinking only water and see what happens. We all read different things about water intake, and how much, obviously water is the best thing to drink. I just about drink only water aside from teh occasional soda or tea - and my skin doesn't look amazing, like articles may say. But it won't hurt to try, well just don't drink A TON in a day because you could get sick.

Water helps flush out toxins. Sodas, juice mixes, etc. are pretty toxic. They may lead to more acne. Like Geeking said, try ditching everything else and see if it helps any. But overall, you're gonna want to find the direct cause of your acne. Like mine was caused by issues going on with my digestive system. I had leaky gut. No doctor helped me figure that out. They would say nothing was wrong, and point me to a dermatologist for expensive and harmful medication.
