I use B5, losd up to 8 to 10gms a day, then maintenance at 3 to 4 gms a day.
As far as meds: one word, TOPICALS. Stay away form Accutane, and, if possible, oral antibiotics. Try clindamycin gel, and/or clindamycin/benzoyl peroxide gel. Also, Retin-A Micro or Differin gel. Effective, minimal toxicity.
