Hi, i just started haloperidal 2 weeks ago. I was on respiridone for 2 months and then they switched me to haloperidol overnight. I have not been able to sleep normally. Its like i have severe insomnia. Will it go away, or should i go back to respiridone (i had sleeplessness) with that one too. I cant take it anymore. I need sleep. Im becoming more suicidal. Im shaking too almost uncontrollably. What should i do? Will these side effects go away soon. If so, how soon?
