Starting low-dose Abilify! What to expect?

My doctor is letting me trial low-dose Abilify! He’s starting me on 2 mg but from what I’ve learned from this group that’s a bit too high. I don’t have the pills yet, but I’m assuming I can cut them into 1/4. In this case, is .5 mg a decent starting dose?

Once I figure out the dose saying, is LDA something that I will notice benefits immediately or does it take weeks and months? Also, is it similar to LDN and that it usually gets worse before it gets better? Anything else I should know?

Thank you all in advance for your comments. I have like zero cognitive spoons and probably won’t be able to respond but read and appreciate them all.
