Be careful going back on Lamictal after being off of it for a few days. It can be dangerous and the official recommendation is to build it up again slowly to avoid the risk of Stevens Johnson and all those other skin conditions you can get. It's extremely negligent of your Pdoc to not refill your Lamictal on time and then on top of that to not bother paying any attention to the cold turkey withdrawal or the build-up back to your old dosage.
