just make sure to read the information slip, and at least here in sweden the recommendation is to not treat headaches with pain relievers more than 9 days per month or it can just cause more headaches.
what i go with is just doing what i can to handle the headache/migraine without medicine, but feel 0 guilt about popping a pill if needed. Especially if i’m going somewhere or have something at home i want to actually enjoy i’ll not hesitate to medicate.
