My hypomanias have not always been fantastic (sometimes, yes it is seemed that way, like shouting out, "I'm a f***** genius with glue gun and marker in hand... um...yeah. My psych said, "but you didn't really mean it did you? I said, yeah, in that moment, yes. I meant it very much...), but sometimes it's just rage and super irritibility. Citalopram was an unmitigated disaster for me. It didn't bring on any positive aspects of hypomania, but completely deranged suicidality. Not just like, oh, yes, but physically compelled toward, and consumed with ways that were just... let's just say...not my way.
Lexapro on the other hand... it was the first thing I was prescribed when misdiagnosed MDD...they said, it might take 3 or 4 WEEKS ...two DAYS later I was all like, holy cow! This is amazing! Should've been a clue. Wasn't.
