I'm not normally on this forum, but I worked with clients who took cloazril for a while. It was several years ago, but some things I heard back then:
1) you definitely need to do this with the help of your pdoc. There are a LOT of risks with this med both on it and coming off of it. I would suggest talkign to your pdoc about the symptoms you are feeling now that you are no longer taking the med. It seriously effects your white blood cell count and any changes in how you take the med could make you more susceptible to physical illness. That may be playing into your tiredness.
2) confirm this with your doctor, but you will likely not get any benefit from this med again if you go back onto it. It's one of those meds that has a weird effect for a lot fo people: it doesn't work again if you ever stop for a longer period of time. I can't remember why this is, but we would hear it from the drug reps too.

Ok, cautions out fo the way, good luck in your med-free endeavors. I went off meds over 2 years ago and it was the best decidion I ever made for myself. It's been difficult at times, but never as difficult as it had been on meds. I hope you have support around you and everything goes well. In case you have not yet heard this TEDtalk, I would suggest giving it a listen. She gives some good resources. Eleanor Longden: The Voices in my Head
