hi there read your query and this is a significant question i wish you had mentioned the measures you took so far anyways i will answer assuming you were on medicines and took no other precautions i am also assuming that your neurologist is right about the diagnosis of migraine you know the easiest way to avoid migraine is to avoid the trigger. every migraine patient usually has a trigger- chocoloate, sunlight, lack of sleep, and sometimes even coffee. So the best thing is to avoid the trigger. very frequently, this itself brings down the incidence of migraine episodes. now the best thing about migraine is that there are many drugs that can be used to treat migraine prophylactically. as you said this includes the antiepileptics. But you can try the lower medicines as well like propranolol, flunarizine etc also, make sure that you do not have sinusitis or vision disorder. these also can masquerade as migraine. and besides a ct scan may be suggested to make sure there is no other symptom personally i would have avoided amitriptiline and anti seizure drugs as far as possible. they have many side efects I hope it answer you Dr Saumya Mittal
