Hi- I am a recovering alcoholic four years sober with Bipolar II diagnosis. I previously was treated with only an antidepressant/anxiety med- lexapro, but 9months ago was put on lamictal 250mg. After the initial slow buildup in dosage I felt pretty stable. Now I am experiencing depression again. I have to get a new psychiatrist, my current one is going on a leave of absence. I am wondering if anyone else has experienced initial positive results and then after a while a recurrence of depression. Anyway- others have asked about "mental fogginess", short term memory loss, mine went away about a month after I reached my current dosage.
