acne
"Doxy is amazing. If you stick to it for a while you will see results like you've never dreamed of. My skin looks GREAT and people compliment it all of the time. I hope it stays like this when I finish the last pill in 3 days. I took 100mg 2x a day for 3 months. Only drawback is the horrible nausea and vomiting I experienced when I didn't take it after or with a meal."
