Very true; Actually I remember getting migraine the night of exam; So in the morning we had an exam 20% of semester grades of that subject; So you see it was really important to study; The migraine didn't stop and this is what all I could try:
1- Two cups of tea.
2- Paracetamol 500 mg;
3- Declomol Powder (I don't really remember its gram)
4- Co-Damol
5- Cold and Heat pack.

All these stuff never helped; I tried to sleep then I fallen a sleep like a dead body from 9:00 PM to exactly 8:50 AM while I had the exam at 9:00 AM. So actually that made a lot of trouble for me; They asked me many things (Questions and papers) until allowing me to do that exam later in another day.

It's unbelievable that all the above didn't stop your migraine.

You can try any pain killer that contains 30mg of Codeine. It's quite strong and effective with pain relief.

I have it but not working even xD
Zapain 30mg codine/500mg paracetamol.

Spoiler:

It's surprising that It doesn't have an effect on your migraines.

There Is "Oxycodone", that treats pain quite effectively but I suggest to not take It. It's highly addictive and very difficult to quit.
