Is it a good or bad idea to tell someone that you are bipolar when you first...

[J c]

...start dating? I do not have a severe case and I faithfully take my medication; however, it still effects my life in different ways. Mostly b/c of high social anxiety, unable to keep a job for more than a 1 1/2 years, and I still have mood swings (much milder than they used to be, but they still exist), and I do not handle change well at all.

So do I give someone an early heads up or do I let them just get to know me? Many of the problems my disorder brings are not visible to most and won't be visible to my date until 6-12 months into a relationship when things start to get serious... ???
