Really depends on you and them. I had someone curse me in February, took me until the first week of July to put it together that the frequent unexplained diarrhea (I even went to the doctor several times and had a lot of testing done) was in fact from a native witch. I did a freezer spell and a mirror box and the symptoms completely resolved within 24 hours. Does it stop her from trying again? eh the mirror box will negate most of it. Believing you can’t stop someone is more than half the battle I think. Self doubt will kill your attempts.
