Dear travellingshowcase, hello.
pain is increased by many trigger factors, some common of these are:-
1. lack of sleep
2. missed meals
both physical or mental
4. excessive exercise
6. dairy products
7. excess chocolates, etc.
You can research which factors trigger your migraine and plan accordingly.
Coming to the medicine effect, Flunarizine
10 mg(Sibellium)at night is beneficial in reducing the frequency and intensity of the attacks. Take it only under medical supervision after consulting your doctor. For immediate relief you can use Paracetamol
and Domperidome .
