for me...HUGE anxiety, looping negative racing thoughts, agitation, I say the EFF word like crazy (and I'm don't usually say curse words) and just highly irritable about everything. Also depression and I had suicidal ideas the one time that put me in the hospital.
The thing that stops all this for me is depakote and seroquel...the last time I had an episode those two meds were like putting ABS brakes on it. I think it stopped in 2 or 3 days (very heavily sedated too) but I did end up depressed for several more weeks before I was able to come back up to stable.
