Doryx
"I started taking Doryx about 4 months ago for cystic acne. SO GLAD I DID. It took almost 2 months to see results but it was definitely worth the wait. It doesn't bother me to leave the house now without makeup. Occasionally I'll still get cysts but they only last a couple of days or so and it's usually around the time of my period. 

I do notice though that it makes me thirsty and it dries my skin/chaps my lips. But it's totally worth it. Just be patient! I almost gave up after the first month. I'm so glad I didn't."
