I've only been on it for a couple of months now (300mg 2x day) but it seems to be working like a charm so far.
Of course, thirsty and peeing all the time when i started out. That only lasted about 2 weeks or so for me.
I've found it actually puts me somewhere between medium and slightly manic mode (but controllable).
I am very unhappy about the lack of libido though. I am married and it does seem to be the side affect that won't go away.

I don't think I had any hallucinations when i started it. Hmm...I hope they are a very temporary thing for you. I'm sure they are unsettling.
