What's working:
Diane-35
Retin-A
Minocin
Dove soap
Loads of water
Neutrogena oil-free moisturizer (sensitive skin)

What didn't:
(ha ha ... where to start!?)
Clearasil & basically any acne stuff in the drugstore
Alesse (Oh gosh, gives me shivers thinking about it!)
Proactive (Ugh!)
Asprin mask (not good for sensitive skin)
High does of various vitamins
Tea Tree (makes my skin worse)
Expensive department store "acne" lines (prescriptives,etc)

Just to say, I now have mild acne ... it's not gone, but something's finally working! Thank you to everyone for posting loads of info along the way! :)
