A lot of the antipsychotics will dull you. As the previous poster said, withdrawal can cause rebound insomnia. It doesn't look like the Geodon or the Zyprexa were working (Zyprexa helped me sleep but left me a zombie) so maybe he could try a mood stabilizer and sleeping pills? You can't have it two ways, either take the meds and be a zombie who sleeps or don't take the meds and be creative and never sleep. Both options aren't the greatest but we all have to get by somehow.
