For what it's worth, I think mood stabilizers are the backbone of treatment for BP---eliminate them, and everything else falls apart no matter how many drugs one is taking. I don't believe it's so much that Lamictal has effects we actually feel, but we'd notice its absence. It's like making a screwdriver: you have orange juice and vodka, but if you don't have a glass, all you wind up with is a mess.

I know it's frustrating when you don't think a drug is doing something for you, and FWIW, I take a good-size amount of Lamictal myself and it doesn't fix everything. But everytime I think it's not doing anything, I remember what my life was like before I started it and realize how much less severe my mood swings are now. I still have them, and I'm still a rapid cycler, but the effect is blunted.......I used to rage at my family, screaming at the top of my lungs until my throat was raw. I don't do that anymore. I also used to bounce off the walls and do silly things like pressure-wash my porch for 4 solid hours. I don't do that anymore either.

Of course, it's up to you but I think taking yourself off Lamictal and not substituting another mood stabilizer would be a mistake. Just my two pence worth.
