When I started on lamactil I had a really manic period, and I actually wrote a novel, of all things, in the space of three weeks. (I'm not saying it was any good.) I was really, really cheerful, but very dizzy, and often felt, how can I put it, drunk. There was a scare when I thought I was getting the rash, but it was a revisit of shingles. Apart from that, lamactil turned out to be good. (Six weeks on, it started working as it should.) All I would say is be careful, and keep an eye on yourself, because everyone reacts differently.
