I have a very good friend who has sz. I'm really worried about her. She's not sleeping much. She's tried almost all of the antipsychotics. She says out of all of them haldol works the best, but it causes brain fog for her really bad. She's extremely intelligent. I just wish I knew how to help her. Ugh...mental illness sucks. But she is taking a high dose of seroquel, but she said she needs to add on haldol bc the seroquel doesn't help all of her symptoms she said. I hope she decides to give it another chance...
