I’ve been on clozapine for around 5 years now and it’s the only antipsychotic that’s ever done anything for me, however it still hasn’t done anything for the voices. A month or so ago while i was experimenting with the supplement ProFrontal (Sarcosine + NAC) I took a stiff dose and it actually reduced the voices and made them quieter, I couldn’t believe it! I’ve been hearing voices 24/7 for 12 years straight. Unfortuately I haven’t been able to get it to do it again, but I think I’m on to something and the ProFrontal is working better and better the more I take it.
