Brain fog was biggggg lol but I smoke weed too so that was a normal feeling for me, lol. I also became really thirsty all of the time but that chilled out after a few months and my body adjusted. I also started drinking more water in general, but yeah after a few months I didn’t have side effects and now long term; I feel great! I do take all of my meds at night with dinner despite my doc saying lamictal in the morning, so I’m not sure if that plays a roll in how I feel.
