I've Been OnAbilify With No Problems For Several Years. Due

I've been onAbilify with no problems for several years. Due to the fact that it has become so expensive my Psychiatrist thinks I should switch over to Ziprasidone 40 mg dose. I am fearful of side effects ON the new med and also feel that "if it ain't broke ,don't fix it" should be the mentality of the Psychiatrist. What do you know about side effects of the drug Ziprasidone?
