Years back when I first started on it ,, I really needed it.. Helped even me out so that I could learn coping skills and ways to self manage Bipolar.
Downside I broke out in hellish cystic acne for the first 6 months then it tapered off a bit, , never went away. I had a really significant tremor. I forgot words left and right , would forget how to spell words like " what"

So after about 1.5 or so years I decided I wanted to try life without it.
I have dropped AP's cold turkey and never had so much as a hiccup .. Coming off Lithium ? Holy hell it was horrible, Sick as a dog for 3 weeks .. Took about 3-4 months for my brain to revert back to pre lithium ..
Was it good over all for me ? Yes at the time. Am I glad I dropped off it ? Yes.
