An acquaintance told me that her daughter was furious at what she experienced with Accutane. It affected her mouth (I'm not sure I remember what she said, but either it was terrible sores, or dry mouth, and she was never the same again.
In general, drugs are scary. You should read the sensiblehealth site and also the field control therapy site, to see what they have to say about how drugs can screw you up.
Also see the depo-provera site, and I'm sure there's many, many more testimonials. Vitamins, supplements, herbs & Tums can also cause ill effects when ingested indiscriminately. People have to educate themselves to the pro's & con's of *anything* before taking stuff on a steady basis.
(Not that I'm educated, rather I've finally learned enough to know to research before "leaping" ;-)
