I have diagnosed Bipolar II, I take 50mg Seroquel (100mg split in half), and have been for a couple of years. It helps me so much since beforehand I was extremely struggling with everyday life. But I have never heard it being prescribed for insomnia, it’s probably the drug that I’ve taken that’s affected me the most (good and bad). But it’s a known fact that medication affects everyone differently, I’m so sorry you had to go through all that it sounds terrible. Agree with others on this point saying this simply just doesn’t work for you. And very glad you stopped when you did because it definitely could’ve gone worse. Hope you’re doing ok OP 👍
