Thank you all for that awesome welcome!

As Innerzone wrote, I also think the delayed effect is a bit fishy. I recall that just prior to I started taking SSRI, I had a period where I felt good and worked like 70 hours a week; totally goal oriented, almost a bit OCDish when it came to being productive. I had to be productive at all time and had a hard time just to relax for the sake of relaxing. But it is so long ago so I don't know if it was hypomania. I have had depressive periods on and off probably the last 6 years, but it isn't until the recent 3 years that I am certain that I have experienced hypomania and it's just the last 2 years that it has really gone out of control.

All in all I think I've only had major depression and hypomania when I'm on SSRI, but then again I've been on it since I was 20 years old (7 years) and I don't recall the first years to be that dramatic. This is what's confusing.

Also; would Lamictal work if I wasn't Bipolar?

50mg did nothing for me either (just a short hypomania episode when I went from 25 to 50). BUT when I finally got up to 200, I was kicked out of the depression. So perhaps it will work for you like this as well.
