Of all the meds, don't go rogue and start playing with your lamotrigine dose. Aside from seizures, when you play around with the dose too much and go up or down too fast/too slow or inconsistently take it you increase the likelihood of getting SJS (Steven-Johnson Syndrome) or its more severe relative, TEN (toxic epidermal necrosis). It's very rare, but that's not something you want to play with. Just look it up on Google images
