This is why I wonder how often you have to have mania, or how bad it is or how long it lasts, to be considered bipolar. Seeing as I've been on most of the SSRIs that are out there and not suffered any extended mania, I doubt I'm bipolar.

But the fact does remain that I experienced mania before I was ever on an SSRI. I can only remember one instance of it, so that doesn't really seem like enough. But one morning when I was around 12 or 13, I awoke to an upbeat, optimistic pop song playing on my clock radio, and I felt like the world was a different place. Everything seemed more vivid. I felt unaccountably happy, and told my mom I wanted to buy a sewing machine and make all my own clothes. I don't remember what else I did, but I do remember that was when I learned what mania was, because my mom was alarmed by my behavior and called it manic.
I hadn't been on any antidepressants yet, but if I remember right, I was prescribed Xanax before this time. I think they had me taking it every day at night, and during the day as needed. Very bad idea, but not sure if that could cause mania.

Other than that one isolated time, I think I have only experienced mania-like symptoms on medication. What happened to me last week was definitely not just "being in a good mood" as my boyfriend suggested. I know when I'm happy, and that was not happy, it was more like a demented, uncontrollable giddiness.
However, it happened three days in a row and not again. A couple mornings I thought I could feel some slight stimulating effects. Like the other day I heard something stressful an hour or two after taking my pill, and my reaction was a little exaggerated. Palms sweating, heart racing, and I was at home, which is usually enough to quell my anxiety.
Nothing else though. I'm hoping they were temporary side effects, but I'm still waiting on a call back from the nurse advice line at my doctor to tell me if I should be concerned about the side-effects, and if I need to get in right away to change my medication.
