I was on it for pschotic episodes but at like 200mg.
Cat's on it for SH related issues at like 25mg.
I guess it just tends to block stuff out and things but I don't know. I do however know of a good website
www.crazymeds.us that can tell you more.
(Mods feel free to get rid of the link if you need too but I'm pretty sure it's safe)
