Just don't. Frequently starting and stopping anti-psychotics such as Abilify is something worth avoiding. With regular consumption of those drugs your brain adapts and sudden discontinuation frequently results in worse symptoms than were originally present.
If you're taking medication such as Abilify, take them regularly about 3 months. If the side effects of the medication outweigh the benefits consider discontinuing the medication. When discontinuing the medication taper your dose down slowly over several weeks.
Part of the challenge in treating people with anti-psychotics is the medications aren't effective at eliminating negative symptoms and have excessive side effects. Often patients understandably choose discontinuing the medication. The complication is sudden discontinuation of psychotropic medications often results in exacerbating the original symptoms temporarily. This is important to say, when discontinuing anti-psychotics taper your dose down slowly over several weeks.
