Hi, as MeditatingMan advises, you'll be wise to talk about that with your doctor. I remember in my very early twenties, however, I had been on Stelazine or Mellaril for just a few weeks, and had to discontinue them myself cold turkey. I had no issues from that.

But it's still a good idea and recommended that you consult your doctor since everyone is different and has different reactions to all these meds. I wish you good luck.
