I've never gone high on Lamictal uppages, but I do tend to go up to some degree with med increases in general. Then it evens out. Or settles in or something. Seem to recall reading where higher doses (not necessarily high doses) of some meds can have different effects than lower ones, even when it seems counter-intuitive. So it might go away with the increase. Are you in good contact with your Pdoc to help keep an eye on it? Anyone else who sees you day to day?
Never heard this one before. Fun visual , but I hope it proves unnecessary.
