Has anyone had Vasovagal Symptoms relieved taking Lamotrigine?

I’ve always had vasovagal problems but never knew about it. My limbic system is potentially overactive as well. I’ve experienced a lot of complex emotional trauma, and although not severe, head trauma relatively frequently as well. I also have had surgery. I started taking Lamotrigine for Bipolar 2 and it magically fixed all of my mood problems immediately, but the crazy thing is that my irritable bowel symptoms went away completely as well as my overactive bladder symptoms, I stopped getting tachycardia from Adderall, and my Emetophobia went away. I haven’t had a bowel flare up ever since started the meds and it’s been 6 months. Has anyone else experienced this?
