bipolar disorde
"Lamotrigine has worked for me, I'm bipolar 2 and other meds have been ineffective.  I have been on 100mg a day for three years with a break for pregnancy.  I have had spots at the times of dose increases and headaches when I have forgotten to take it. I do occasionally up my dose for a few days if I'm feeling down, this seems to stop a depressive episode from developing. After a few days I drop the dose down again and seem to go on as before. Overall I feel normal and would be lost without this medicine."
