Hi, I'm on Lamictal and haven't noticed that it causes insomnia for me, it makes me sleepy. I think some people do refer to it as "activating", though. You're on the tiny dose of Lamictal because of a withdrawal difficulty? If it does cause insomnia for you, what about taking it in the morning?
The "depression anger"...how do you know you don't have bipolar disorder?
Do you know that the smaller doses of Seroquel help to induce sleep more than the larger doses do? So 50mg., 25mg., even 12.5mg. I am with you on not wanting to get stuck on Seroquel, especially on a dose over 25mg.
One more question: Why did your pdoc remove Lamictal and wants you to take Depakote instead?
Sorry for all the questions, I'm trying to better understand your situation.
