Hi FineandDandy.....my daughter is on Lamictal and that works out well for her. It is not only weight neutral but has a GREAT profile when it comes to side effects. Only thing is it has to be titrated up slowly due to a bad rash associated with giving it too quickly and may take time before it really starts to work. IT is also great in terms of addressing the depressive side of BP and is used to treat people with Major Depression as well. My daughter had more depressive symptoms that when treated with just an antidepressant alone triggered hypomania.
She is on the Seroquel as well (which by the way is an antipsychotic used for mania) which works well in combination with the Lamictal. IN time I am hoping that we can get her off the Seroquel and that the Lamictal will work on it's own.
Hope that you find the med that works good for you.
