Hi,
I have migraines and I am on low-dose Abilify (4mg/day).
Abilify has helped somewhat with depression. (Adderall has helped more.)
I have had weight gain with Abilify. The associated 24/7 hunger has decreased now that I have added Adderall.
I also take Abilify for C-PTSD, not only for depression.
I have seen where some people do not gain weight with Abilify, so it's an individualized response.
I became dystonic beyond tolerance at 6mg and above.
This is just my experience with Abilify.
