"doxy is amazing. if you stick to it for a while you will see results like you&#039;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&#039;t take it after or with a meal."
