"i&#039;ve been taking doxy for a while until my face cleared up and i just had a lot of scarring on my face. later on (mid-december) i starting to break out again and i had leftover doxy. it doesn&#039;t seem to be as effective as before but it definitely works. you have to be patient and take when needed. i take 2x daily. you really want to eat a meal with this medication, not eating a meal could will you make you feel nauseous and could make you throw up."
