Went down from 10mg of abilify (aripiprazole) to 5 for 1 day then stopped completely. week and a half later took one more 5 mg then stopped. will something bad occur

Maybe: Assuming you don't have an illness that needs Abilify (aripiprazole) to control symptoms, then you will be fine. On the other hand, majority of psychiatric illness will get worse unless medication is continued. This will be very very bad. If your doctor did not recommend you stop Abilify (aripiprazole), you will be wise to to talk to your doctor and figure out a better treatment, if you don't like Abilify (aripiprazole).
