@Tina3000 Invega is already OUT of your system. You even said that yourself. Your problem is not Invega anymore. If it was so, you would still need to wait. But as you are taking Seroquel, we really CANNOT say what causes your symptoms. If it's Seroquel or Invega. As long as you are taking Seroquel we can't give you an answer to your questions. You cannot take an antipsychotic and expect the symptoms from another antipsychotic to vanish. It's just not logicall. You can't treat fire with fire. It is your decision what you are going to do, but I recommend you to get rid of Seroquel as soon as possible as it affects you in the same way Invega did.
Go to "adfd.org" they will help you to taper off Seroquel. There you will find people who know more about Seroquel. Ask them for help. We cannot help you with your questions, because we cannot say if it's still Invega that's causing your symptoms. Even if you say that you're sure about that, the only thing we could say is to hang on and wait for the symptoms of Xeplion to relent. But in your case we cannot say that time is the solution, because you're taking Seroquel.
