Headache is a very common side effect of primidone. Caffeine does not headache. Caffeine can cause decreased sleep,
restlessness,
nervousness, nausea, vomiting, and gastric irritation. Primidone is used both for seizure and
essential tremor.
If headache is intolerable then we have two options:

Propranolol is a prescription based medicine.
