Is lithium worth it?

Edit: Thanks for all the reviews!! It helped me to build the courage to give it a try. Will do my first blood test this week :))

My psychiatrist wants to put me on lithium it's been around uuh... 3 months? I never went to do the blood test to start it and I've been pushing it away all the time.

Truth is, I heard a bit here and there about how good lithium is, but I'm very afraid of it. Not even because of the side effects tbh, but ig that the starting something part is scaring me away.

Is lithium really that good? Are there different meds that worked better for you?

Rn I'm on 200mg Lamictal, 300mg Seroquel and 2mg Prazosin.
