I took Dianette for acne & mild hormonal imbalance, about 14 years ago. I was on it for just under a month. Started getting dizzy, headaches, got really bad, one night it suddenly felt like the side of my head had been smashed in, the pain was horrific & I couldn't move one side (arm, leg, face) or speak properly. Turned out (after brain scans had ruled out tumours & a stroke) something called hemiplegic migraine. I still get them, probably will for life. Medication controls them mostly but I can't risk another child, when I got pregnant with DD, we didn't realise the medication can cause multiple birth defects (thankfully she is fine but we were damned lucky). There's a host of other equally lovely side-effects, too.
I'm sure most people are fine on it. I wasn't. My neurologist said, if I'd stopped taking it after the first (very mild) migraine which I hadn't even recognised as a migraine, never having had one before, I might have been fine. I know you wanted positive stories, sorry. But I wish someone had warned me, it's really not been a good thing in my life. If the NHS collapses & I can't afford the medication I will become disabled & in constant pain.
If your skin is a massive problem, have you considered roaccutane? I've had 2 full courses of it. My skin is still not perfect but it's so much better than it used to be. I needed my GP to refer me to a dermatologist to get it. You will also need to be on absolutely bombproof birth control as this stuff is really toxic & causes catastrophic birth defects. But it is very good & one course usually works for most people.
Also have you looked at the long-running skincare thread in style & beauty? Whether for now, if your skin clears up if you do manage ok on Dianette, if you go for Roaccutane - whatever really. There's a poster called Botemp who's really helpful & knowledgeable about all that sort of stuff. My skin has improved no end since I changed my routine.
