Can't imagine that what you've said will seen as offensive -- at least, not here.

Agreed that proper doses of lithium won't make you dopey -- when I get dopey on lithium, it's because the depressive cycle is gearing up again. It definitely irons out the highs of a hypomanic swing, but it doesn't flatten you out entirely like some other meds do. And it's one of the oldest meds around, so its effects are well-known. I recommend it for the mental impact if you can handle the physical impacts (which are slight, IMO).
