I was on Abilify for about a year. I do not recall experiencing any tremors. I just did a brief search on Pub Med Central of the National Library of Medicine of the National Institute of Health. The only articles I found related to the concatenation of Abilify and tremors; were a meta-analysis of children and adolescents taking Abilify, and reports of some of these patients experiencing extrapyramidal side-effects; and an article regarding the pathophysiology of medication-induced tremors. I was surprised to find such a paucity of literature concerning the matter. It seems like there needs to be more research.
Anyway, I know this reply is late, but I hope you are feeling better.
