rosacea
"I've had mild Rosacea for 20years but it really started to flare up when I was 52.  My Dermatologist prescribed Metrogel and Oracea for 3 months after two weeks of Doxycycline 100mg 2x day.  My skin cleared up in about 3 days.  My insurance won't pay for the Metrogel or Oracea so I just continued to take the Doxy 100mg once a day, now I chop it in half and take 50mg a day.  My skin is still clear.  I'd rather take it than the other two (topical and oral) combined.  Cheaper too."
