Sumatriptan isn't a cure-all for migraines. I suffer from near-constant migraine-like headaches (sometimes diagnosed as migraines, some not - depends on the consultant), and they are actually worsened by sumatripan. Morphine seems a little strong, but having tried every offered non-opiate medication (amitriptalyne, sodium valproate, gabapentin, propranolol, topiramate etc.) and only had any success with opiates (tramadol and codeine), it doesn't seem that unlikely.
