Brief Answer:
Take consultation of a neurologist

Detailed Answer:
Hello,
I have gone through your question and understand your concerns.
For recurrent episodes of migraine it is advisable to take prophylaxis treatment along with abortive therapy.
You should take preventive steps like timely food, proper sleep, avoiding fasting, excessive tea or coffee.
For prophylaxis you can take amitryptiline or propranolol or Flunarizine or Topiramate or divalproate.
Zomig can be taken for infrequent attacks. Online medication delivery sites are available but most require prescription. Unfortunately we don't dispense medicines or prescription from this website.

You can check for such online sites delivering in your country.
Hope you found the answer helpful.
Do get back to me for further queries.
Regards
Dr N Kumar
Neurologist
