I'm bipolar. The usenet post referenced contains advice that would literally be considered medical malpractice if a doctor uttered it: Try to avoid medication if possible.
If you're truly bipolar, you need medication. This is not my opinion, this is the current obligated medical treatment.
What I have seen from my bipolar friends who go off their meds has often been horrifying. It's incredibly common, unfortunately, largely stemming from beliefs like this post posits: it's just a discipline issue, it's a phase, it's an attitude, etc.
As always, try to avoid medical advice from usenet posts. Your loved ones will thank you.
