im in irvine too.. planning on going in today to see dr. gitter.. a friend of a friend got his card there so hopefully ill get it.
i have no medical documentation, but ive had trouble sleeping all my life... that and anxiety and depression, which all seem to be valid reasons according to my research... not sure if ill use the depression thing since that seems a lil iffy but yeh.
heres a link to a site with various doctors in the area.
