I've been on Lamictal 4-5 yrs now with no significant side effects. I do have excessive daytime sleepiness (that I take meds to combat) but I don't know if is specifically from the Lamictal of the Abilify. Lamictal is supposed to help with depression (I have bp I) & it seems to be doing its job, despite one winter when I had to add Wellbutrin. I got off the Wellbutrin in the spring. I must have a touch of SAD, too. I now sit under one of those full-spectrum lights in the winter.--Suzy
