Yes this happened to me years ago I was manic, I am no longer manic it is will controlled with Lithium my wonder drug. My doctor said that antidepressants without a mood stabilizer can increase mania but im' wondering if it can actually cause it, I have no insurance and no doctor to ask so i'm just tossing my thoughts out there for my peers to see what they think, it kind of makes sense if anti depressants lift ur mood that it could cause mania is what I'm thinking. HUGS.
